MATHEMATICS STANDARDS A PA R E N T ’ S H A N D B O O K O U R C H I L D R E N , K - 5 Published by the Pittsburgh Council on Public Education Community Champions for Children’s Achievement 2 What your child should be learning: INTRODUCTION WHAT SHOULD MY CHILD BE LEARNING? The elementary mathematics curriculum taught in your child’s school is “Everyday Mathematics.” That means the classroom activities and assignments for kindergarten through fifth grade should reflect those described in this handbook. “Everyday Math” is designed to encourage children to think mathematically and to develop confidence and familiarity with math concepts and skills by using numbers and activities that have meaning in children’s lives. Children learn about inches and centimeters by measuring their own hands, for example. They discover negative numbers by reading an outdoor thermometer and charting the daily temperature. They may find an average of the lengths of their classmates’ shoes. And they find decimal numbers in a handful of real coins. In kindergarten through third grades, classroom routines reinforce this everyday learning (see “Classroom Routines”). At all grade levels, students play a variety of math games that give them plenty of practice using numbers. Everyday Math, which is based on research about how children learn, is structured differently from the math many parents learned in elementary school. It does not involve presenting a skill or concept to students, expecting them to master it within a certain time period, and then moving on. Instead, a teacher introduces a mathematical idea that children will come back to again and again before they leave elementary school. For example, kindergarten students may work with their teacher to make a simple graph showing how many children in the class have a birthday each month. A fifth grade student may demonstrate the same skills in gathering and graphing data in much more sophisticated ways, by designing a survey, administering it to classmates, and interpreting and graphing the results. In keeping with the structure of the curriculum, teachers also have different ways of assessing Everyday Math students throughout the year. Because young children’s learning is gradual and their progress tends to be uneven, teachers rate their work as: • “Beginning”—The student is not able to complete the task independently. He/she shows little understanding of the concept or skill. • “Developing”—The student shows some understanding, but needs reminders or suggestions to complete the task without errors. • “Secure”—The student is able to apply the concept or skill without any help. CLASSROOM ROUTINES In grades K-3, classroom routines and daily activities show students how math is used in everyday life and help them practice skills, such as: • Calendar activities. Students practice PROBLEM-SOLVING TASK FOR GRADES 1-3: MAKING APPLE JUICE As a rule of thumb, you need 3 apples to make 1 glass of apple juice. • About how many apples would you need to make 2 glasses of juice? ...To make 3 glasses of juice? ...A glass of juice for each person in this classroom? • If we have 1 dozen apples, about how many glasses of juice could we make? • If we have 2 dozen apples, about how many glasses of juice could we make? recognizing numbers on a calendar. (“What is the date of the third Tuesday? How many days are in September?”) • Taking attendance. Each day, children record the number of students who are present and the number who are absent. These numbers can be used to create “number stories” (word problems) and graphs. • Documenting the weather. Students record the temperature every day in both Fahrenheit (68°) and Celsius (20°). The class discusses what type of weather they are having that day—sunny, cloudy, rainy, snowy—and documents it with a colored square on a number line or graph. This information can be used to find patterns in temperature or weather. In third grade, students chart sunrise and sunset times and graph changes in the length of daylight during the school year. • Number line activities. For many activities, students refer to the number line that circles the room, counting off the days of the E x ample of s e c on d gr ade w or k w it h t e ac he r ’s c omme n t s Introduction 1 3 CONTENTS After deciding what approach—or combination of approaches—to use, students plan and carry out their strategies to solve the problem. WHAT IS IN THIS HANDBOOK? school year. For example, the teacher may say, “Today is the thirty-eighth day of school. How many ways can we show 38?” Students can also refer to the number line when they recite facts as a class, such as rote counting by ones forward and back from given numbers or “skip-counting” by twos (2, 4, 6…), fives and tens. Reviewing out loud helps students remember facts they are learning. • Daily schedule. The daily schedule provides opportunities for students to practice telling time and to develop strategies for solving problems about time. “If music class starts at 10:30 and ends at 11:10, how long is music class?” “How many minutes until lunch time?” PROBLEM-SOLVING Problem-solving is a key component of Everyday Math at all grade levels (see the example on page two). Students make important decisions about how to solve problems, rather than just following steps that they have been shown to find an answer. They learn to choose from a range of strategies, including: • Describing a computation problem as a “number story” (word problem) • Using objects (laying out counters to represent three times three, for example) • Drawing a picture (drawing six birds and four worms to find out how many birds won’t get a worm, for example) • Using relation symbols, such as “2+2=4,” “10-3=7” In this handbook, you will find an outline of the math standards—goals and expectations for students—for each grade level. To show the types of activities that build these skills and concepts, information for each grade level includes a sample of student work, an example of a game students play, and an example of a homework assignment. In grades one and two, the example of student work has a related “rubric” (a grading or scoring guide). On page 18, you will also find a glossary with definitions of words that may be used by your child’s teacher in the context of the Everyday Math curriculum, or that may be part of homework assignments. This handbook is only an outline to be used as a resource by parents. For more information about grade-level goals or the Everyday Math curriculum, ask your child’s teacher or principal. A note about the games. The games included for each grade level are samples, to show how the games relate to skills and concepts students are learning. (In the classroom, the teacher gives students game directions verbally.) The descriptions here can also serve as guidelines for playing at home. Ask your child to show you how to play “Name that Number,” “Broken Calculator,” or another favorite game. A note about homework assignments. Examples of homework assignments are presented here to illustrate the goals of the curriculum. They are not exact copies of assignments your child may bring home. Homework assignments in kindergarten through third grades that involve home activities are called “Home Links.” In fourth and fifth grades, they’re called “Study Links.” INTRODUCTION ........................................ 2 STANDARDS BY GRADE LEVEL: Kindergarten ................................................ 4 Grade one .................................................... 6 Grade two .................................................... 8 Grade three ................................................ 10 Grade four .................................................. 12 Grade five .................................................. 14 WHY HAS MATH INSTRUCTION CHANGED? .............................................. 17 GLOSSARY .................................................. 18 © 2002 Pittsburgh Council on Public Education A copy of the official registration and financial information of the Pittsburgh Council on Public Education may be obtained from the Pennsylvania Department of State by calling toll free, within Pennsylvania, 1/800/732-0999.

Count backward from 10 to 0. Read and write numbers from 0 to 100 or higher. Know the values of a penny, a nickel, a dime and a quarter. S H O U L D . . . to give to her group. How many more pencils must she find?” • “Tom has 7 cookies. Carla has 5 cookies. Who has more cookies? How many more cookies?” • “There are orange sections for snack today. Keisha, Greg and Mike have 6 orange sections to share equally. How many orange sections can each child have?” Verbally explain or use objects or pictures to show how a problem was solved. ADDING AND SUBTRACTING Make “number families”—combinations of numbers that add up to the same number— up to the 5 number family. (For example, the “3 number family” is 0+3=3, 1+2=3, 2+1=3, 3+0=3.) PROBLEM-SOLVING Using pictures or objects, solve simple “number stories” (word problems) that involve: • Counting. “How many students are in class today? How many snacks do we need to give one snack to each person?” • Adding. “Zack had 9 pennies. Then he earned 2 more pennies. How many pennies does Zack have now?” • Subtracting. “Zack had 11 pennies. He spent 6 pennies. How many pennies does Zack have now?” • Matching. “There are 6 birds and 4 worms. How many birds won’t get a worm?” Create simple number stories for numbers less than 20. Using pictures or objects to model the problem, solve more complex problems such as: • “Shakeia has 2 pencils. She needs 6 pencils MEASURING Compare sizes of objects. Which is bigger, heavier, taller, longer? Tell time to the hour, using a clock with hands and a digital clock. SAMPLE HOMEWORK Make a “number family” for the number 5. Example: The number family for 5 is all the combinations with a sum of 5—0+5, 1+4, 2+3, 3+2, 4+1, 5+0. COLLECTING AND GRAPHING DATA Make simple bar or picture graphs. For example, the class might graph students’ birthday months using pictures of birthday cakes. Make observations and answer questions about simple graphs. (“How many students have a birthday in January? Are there more birthdays in January or more birthdays in June?”) Kindergarten MATHEMATICS SAMPLE OF STUDENT WORK SAMPLE GAME “MONSTER SQUEEZE” Assignment: Record and graph students’ heights. Explanation: With the teacher, students measure and record their heights and the teacher graphs the information. As a class, they discuss the results. Tools: Two pictures of monsters, a 0-10 number line (“0-1-2-3-4-5-6-7-8-9-10”) Number of players: 2 or more Rules: Place the monsters at either end of the number line. The teacher or a student thinks of a number between 0 and 10. Another player guesses the number. The first player says, “Your number is too large” and moves the right-hand monster to cover the guessed number, or “Your number is too small” and moves the left-hand monster to cover the guessed number. The other player(s) keep guessing until the correct number has been “squeezed” between the two monsters. Players take turns thinking of a number and moving the monsters. Example: Ms. Brown thinks of the number 4. Ken guesses 7. Ms. Brown says, “Your number is too large” and places the monster on the 7. Ken guesses 2. Ms. Brown says, “Your number is too small” and places the other monster on the 2. Ken sees that the number is between 2 and 7 and he correctly guesses 4. Now it’s his turn to think of a number. 5 6 What your child should be learning: FIRST GRADE GOALS F I R S T G R A D E G R A D U A T E S NUMBERS Count, read and write numbers from 0 to 1,000. Count by 2s, 5s, and 10s forward and backward, with and without a calculator. Recognize the largest and smallest number that can be made with two or three digits. (“What is the largest number I can make with the digits 5, 3, and 8? 853. What is the smallest number? 358.”) Name numbers as even (2, 4, 6…) or odd (3, 5, 7…). Count combinations of pennies, nickels and dimes and add the amounts (Two nickels plus one dime equals 20 cents. Three nickels plus one penny equals 16 cents). Show equal values with coins (one dime equals two nickels, or 10 pennies, or one nickel and five pennies). Use the symbols for greater than (3>1), less than (3<10), and equal to (4+1=3+2). Write own telephone number and address. ADDING AND SUBTRACTING Begin to memorize basic addition and subtraction facts (5+5=10, 5-2=3). S H O U L D . . . Using a number chart, add and subtract 10 and multiples of 10 from given numbers (40+10=50, 40+20=60). 2 1 11 12 21 22 31 32 41 42 51 52 61 62 71 72 81 82 91 92 101 102 3 13 23 33 43 53 63 73 83 93 103 4 14 24 34 44 54 64 74 84 94 104 6 5 15 16 25 26 35 36 45 46 55 56 65 66 75 76 85 86 95 96 105 106 8 7 18 17 28 27 38 37 48 47 58 57 68 67 78 77 88 87 98 97 107 108 9 19 29 39 49 59 69 79 89 99 109 0 10 20 30 40 50 60 70 80 90 100 110 Number Chart Show different ways of expressing a two-digit number (30+6=36, 40-4=36, 10+10+10+5+1=36; |||| ||||=10; D [dime] + Q [quarter] =35). PROBLEM-SOLVING Solve one-step addition and subtraction “number stories” (word problems). Create simple addition and subtraction number stories. (“Five birds were sitting in a tree. Two flew up into the air. How many are in the tree now?”) Solve addition and subtraction problems with more than one step using pictures or objects. (“I have 20 books. I gave Kim 10 of them. Then I lost two. How many do I have now?”) Verbally explain or show how the problem was solved, using pictures or objects. PATTERNS AND MATHEMATICAL REASONING Find missing numbers in a pattern (2, 4, 6, __, 10, __, 14, 16). Find patterns (such as odd and even numbers, multiples of 2, 5 and 10) on a number line (< 1-2-3-4-5 >) and a number chart. Recognize and follow number patterns to solve problems. Create and continue visual patterns with pattern blocks (▲ ▲ ▲ ▼ ▲ ▲ ▲…). GEOMETRY With straws and twist ties, make simple 2dimensional shapes such as triangles, rectangles, and squares. MEASURING Order objects by length—from shortest to longest, for example. Order objects by weight—from heaviest to lightest, for example. Read a thermometer to find the daily temperature. Tell time to the hour, half hour, and quarter hour. COLLECTING AND GRAPHING DATA Use tally marks ( |||| | ) to record data. Make simple bar or picture graphs. Make observations and predictions from simple bar or picture graphs. (“Today’s temperature is higher than yesterday’s. Tomorrow it might be even higher.”) First Grade MATHEMATICS SAMPLE HOMEWORK SAMPLE GAME Count a handful of coins for someone at home. Record the total. “BEAT THE CALCULATOR” SAMPLE OF STUDENT WORK AND RUBRIC (SCORING GUIDE) Tools: Calculator, pair of dice or deck of cards Number of players: 3 NUMBER STORY Assignment: Write a number story (a word problem) and show your answer using words and pictures. Rubric: Secure (able to apply the concept or skill on their own): The number story includes a question, a “number model” that answers it (2+2=4, for example), a picture illustrating this, and a “unit box” (a box indicating the object or item being counted, in words or a picture). The student created the story and answered the question correctly without needing assistance. Developing (in the process of developing understanding): The number story contains most of the elements described above, but not all. For example, the unit box may have been omitted, the picture may not adequately represent the number story, or the student may have answered the question numerically without actually writing the question to be answered (as in this example). Beginning (just starting to explore a concept or skill): The number story is not complete and/or the elements don’t support each other. For example, the units in the drawing don’t match the numbers the student has written. The student needed a great deal of help to complete the task. Rules: One player is the “Caller,” a second player is the “Calculator,” and the third player is the “Brain.” The “Caller” uses the dice or draws two cards from the deck to create an addition problem. The “Calculator” solves the problem with a calculator while the “Brain” solves it without a calculator. The “Caller” decides who solved the problem first. Students take turns playing each role. Example: Dawnita, the “Caller,” rolls a 6 and a 2 with the dice. Jonathan, the “Calculator,” enters the problem into his calculator (6+2) while Tyler, the “Brain,” tries to solve the problem mentally. Tyler quickly raises his hand and tells Dawnita that the answer is 8. 7 8 What your child should be learning: SECOND GRADE GOALS S E C O N D G R A D E G R A D U A T E S S H O U L D . . . NUMBERS Add 3 one-digit numbers mentally. Count by 2s, 5s and 10s forward and backward from any two- or three-digit number (54, 52, 50, 48…). Memorize basic addition and subtraction facts. Identify “place value” in three-digit numbers. For example, in 387, 3 is in the 100s place, 8 is in the 10s place and 7 is in the 1s place: 387=300+80+7. Write two-, three-, and four-digit numbers when they are read out loud. (“Seven hundred twenty four” = 724.) Read two-, three-, and four-digit numbers. (724 = “Seven hundred twenty four.”) “Shade in” a fractional part of a whole and name the part that is shaded-in. Complete a “Frames-and-Arrows” puzzle with someone at home. (See the Glossary on page 18 for more information.) Multiply numbers by 1 and by 10 (1x7=7, 10x7=70). Know the values of a penny, a nickel, a dime, a quarter, a half-dollar, and a dollar. Show coins for a given amount, using pennies, nickels, dimes and quarters. Solve “number stories” (word problems) involving money. (“I had two dollars and my mom gave me a quarter. How much do I have?” “I spent 75 cents on candy. I paid with one dollar. What’s my change?”) Show equal values with coins. (One quarter equals five nickels, or two dimes and one nickel, or two dimes and five pennies.) Use a calculator to add and subtract money amounts, as decimals (.25+.36=.61). one-third SAMPLE HOMEWORK PROBLEM-SOLVING PATTERNS AND MATHEMATICAL REASONING Recognize patterns and relationships between numbers, such as odd and even, or multiples of two, five and ten, or doubling or halving a number. (See the sample homework.) ADDING, SUBTRACTING, MULTIPLYING Make up number stories for a given equation. (“Write a number story for 78+22=100.”) Understand that there are many ways to show a number. (50 can be shown as 25+25, 100-50, 10x5, two quarters. 125 can be shown as 100+25, 175-50, 50+50+25.) Solve multi-step problems. (“I bought two apples for 50 cents each. I also bought a banana for 35 cents. How much did I spend? I paid with two dollars. What’s my change?”) Identify common 3-dimensional shapes such as prisms, cylinders, cones and spheres. Write addition “turnarounds” (4+3=3+4) for given facts. Write “extended” addition facts (since 4+3=7, then 40+30=70, and 400+300=700). Solve simple multiplication problems (“There are three baskets. Each basket has five eggs. How many eggs in all?”) using common strategies such as: Find the perimeter (the sum of the length of Make up “fact families” (the fact family for 4, 3, 7 is 3+4=7, 4+3=7, 7-4=3, 7-3=4). Make up “extended” fact families (30+40=70, 40+30=70, 70-40=30, 70-30=40). • Drawing a picture Use a calculator to add 3 or more two-digit numbers (17+24+56=97). • Making a table GEOMETRY Using a ruler or straight-edge, draw a line between two given points (a “line segment”). perimeter • Creating a model using objects area • Guessing and checking the answer • Looking for a pattern Second Grade MATHEMATICS the sides) of a shape by counting units. Find the area (the measurement of the inside of a shape) by counting units. MEASURING Tell time to five-minute intervals. Measure objects in inches, feet, centimeters, decimeters and meters, using a ruler, a tape measure, a yardstick or a meter stick. Find dates on a calendar. (“If today is Tuesday, November 7, what date will next Tuesday be?”) COLLECTING AND GRAPHING DATA Plot data on a bar graph—the number of books read in one week by students, for example, or the height and weight of every student in the class. Compare bar graphs—the number of books read during the first week of October, for example, compared to the number of books read during the third week of January. SAMPLE OF STUDENT WORK AND RUBRIC (SCORING GUIDE) CREATING SHAPES OF A GIVEN AREA Assignment: Using a template (a tracing/ measuring tool), draw five shapes that are different, but that have the same area. Rubric: Secure (able to apply the concept or skill on their own): There are five different shapes. Each shape has the same area. Each shape is labeled with the correct area. The shapes are drawn using a template. The student can explain verbally how he or she found the area of the shapes and can explain different attributes of the shapes. Developing (in the process of developing understanding): There are four to five shapes, but they have only small differences. Most or all shapes have the same area and are labeled with the correct area. The student can explain verbally how he or she found the area of the shapes and can explain different attributes of the shapes, with some prompting. Beginning (just starting to explore a concept or skill): There are four to five shapes, but they aren’t different or the shapes don’t have the same area. Shapes are labeled with the area with one to two mistakes. Most shapes are drawn with a free hand instead of a template (lines aren’t straight). The student needs help in thinking about how he or she found the area of the shapes and how to explain different attributes of the shapes. SAMPLE GAME “NAME THAT NUMBER” Tools: Deck of cards with the Queens labeled as zero, the Aces labeled as 1, and the other face cards removed Number of players: 3 or 4 Rules: Players try to find different ways of expressing a number on a drawn card by adding or subtracting the numbers on other randomly drawn cards. Example: Ashley shuffles the cards and places five cards face up on the table. She places the rest of the deck face down on the table and turns over the top card. This card, the number 8, is the “number to be named.” Tawnya tries to find a different way to display the number 8 using the five cards on the table. She chooses a 9 and a 1 and tells the others that “9 minus 1 equals 8.” She takes all three cards and replaces them with three new cards from the deck. Ben tries to name the next card using the cards on the table. If he can’t create a problem to match the number, he loses his turn and the cards are set aside. The children take turns playing until there are not enough cards left in the deck. 9 10 What your child should be learning: THIRD GRADE GOALS T H I R D G R A D E G R A D U A T E S NUMBERS Count forward and backward by 10s, 100s, and 1,000s from any four-digit number. Identify “place value” in three- and four-digit numbers. For example, in 1458, 1 is in the 1000s place, 4 is in the 100s place, 5 is in the 10s place and 8 is in the 1s place: 1458=1000+400+50+8. them equally between five people.

If each child drinks Third Grade 11 MATHEMATICS about a half pint of milk each day, how many children are in the daycare center?”) PATTERNS, SEQUENCES AND MATHEMATICAL REASONING Use knowledge of addition, subtraction and “fact extension” (if 3+2=5, then 30+20=50) to solve problems. Use a calculator to count by 1000s, 100s, and 10s to review patterns in place value (4567+1000=5567, 5567+3000=8567). Use a number chart to find differences between pairs of numbers. MEASURING GEOMETRY SAMPLE GAME Identify similarities and differences among 3dimensional shapes. “BROKEN CALCULATOR” Recognize right angles. Tools: Calculator Using straws and twist ties, create and name some polygons (2-dimensional figures made up of line segments). Number of players: 2 EXPLORING DATA AND CHANCE Understand simple data analysis. For example, the class counts the letters in everyone’s first names and looks for the range (the difference between the greatest number of letters and the smallest number of letters) and the median (the number of letters that falls in the middle). Tell time to five-minute intervals and oneminute intervals. Show familiarity with the metric units centimeter, decimeter, meter, and kilometer. Show familiarity with the U.S. units inch, foot, yard, and mile. Use a ruler to measure inches and centimeters. Know some equivalent measures, such as the number of inches in a foot and the number of centimeters in a meter. Show familiarity with different types of scales for measuring weight, such as balance scales and bathroom scales. Identify basic units of weight measure in the U.S. and the metric systems: ounce, pound, gram, kilogram, and liter. Example: Kyle chooses the number 9 as the broken number. Jasmine enters 3x3 into the calculator. SAMPLE OF STUDENT WORK “FUNCTION MACHINE” Assignment: Figure out the rule, write the rule in the “function machine” and complete the “in/out box.” Explanation: The “rule” describes what the student does to find the number. In this case, the student is given “8” and “28:” the rule is “+20.” The “function machine” is a fun way for children to understand the relationship between addition and subtraction—you put “+20” into the function machine and the answer comes out the other end. Or, if the function machine shows what comes out, the student determines what must have been put in. The “in/out box” is a diagram showing the results of using the function machine.

PROBLEM-SOLVING Use and explain strategies for solving multiplication and division “number stories” (word problems). SAMPLE HOMEWORK Make a list of all the people in your family. Include all the people living at home now and any brothers or sisters living elsewhere. The people who live at home do not have to be related to you. Write your own name on the list too. You will need this information to learn about the sizes of families in your class. Note: This homework assignment contributes to a class activity on family sizes. The class makes a graph showing the “Number of People in Our Families” and answers questions about the largest number of people in a family, the smallest number of people in a family, the mode (the number that occurs most often), and the median (the number that would fall in the middle if all the numbers in the set were laid out in order). Create multiplication and division number stories. ADDING, SUBTRACTING, MULTIPLYING, DIVIDING Know basic addition and subtraction facts from memory. Identify and use square numbers (52=5x5). Solve problems with more than one step using one or more familiar strategies, such as creating a model, making a table, looking for a pattern, or drawing pictures.

You don’t have a compass that is big enough!”) PATTERNS, SEQUENCES, AND MATHEMATICAL REASONING Explain the relationship between multiplication and division. Use tables of data to solve problems. Know basic multiplication facts from memory. Know “extended” multiplication facts (if 2x3=6, then 20x30=600). Use rate tables to solve problems. (“Jen received an allowance of $8 in 4 weeks. At this rate, how much allowance did she receive per week?”) Use a calculator to rename any fraction as a decimal or a percent ( 3/4=.75, or 75%). Jen’s Allowance Estimate the magnitude (greatness in size) of answers to multiplication problems. (“A blue whale weighs as much as about 425,000 kittens. About how many kittens weigh as much as 4 blue whales? Estimate if the answer is in the 10s, 100s, 1000s, 10,000s, 100,000s, or 1,000,000s.”) Week Amount 1 2 3 4 $8.00 One example of a rate table * For more information, ask a teacher to explain strategies your child may be using.

TRAIL MIX (FROM THE FOURTH GRADE NEW STANDARDS REFERENCE EXAM) Assignment: Tran and Jenna are members of a hiking club. They are using this recipe to make trail mix for their club to take on a hike. Raisins Peanuts Shredded Coconut 1 cup 2 cups 1/2 cup Number of players: 2 or 3 Rules: Players try to find different ways of expressing a number on a drawn card by adding, subtracting, multiplying or dividing the numbers on the cards they have been dealt. 16 7 5 8 2 10 Example: Rob shuffles the cards and deals 5 cards to himself and 5 to Brittany, the other player. From the remaining deck, he turns over the top card, a 16. This is the “target number.” Brittany tries to find a different way to display the number 16 using as many of her cards as possible. She has the cards 7, 5, 8, 2 and 10. Using four of her cards, she displays 7x2=14; 14+10=24 ; 24-8=16 SAMPLE OF STUDENT WORK Trail Mix Recipe (Enough for 1 bag): Tools: Deck of cards with the Queens labeled as zero, the Aces labeled as 1, and the eight other face cards (4 Kings, 4 Jacks) labeled as 11 through 18. The 2s through 10s have their own values. They bought: 3 pounds of raisins—enough for 12 cups 5 pounds of peanuts—enough for 18 cups 16 ounces of shredded coconut—enough for 5 cups (continued on page 16) She records her solution on a sheet of paper and sets aside the cards she used. After Rob takes his turn at displaying the number 16 with his cards, both draw new cards from the deck to replace the ones used. The 16 goes to the bottom of the deck and the top card becomes the new target number. The player who sets aside the most cards wins. 14 What your child should be learning: FIFTH GRADE GOALS F I F T H G R A D E G R A D U A T E S NUMBERS Determine whether a number is prime (a number greater than 1 with exactly 2 factors: 1 and itself, such as the number 7) or composite (a number with more than one factor, such as the number 14). (Factors are numbers that are multiplied to equal a given number.) Find equivalents for whole numbers (40, 20x2, 37+3…). Find equivalent fractions (2/3 is the same as 4/6) and rename fractions in their simplest forms (8/16 is 1/2). Rename familiar fractions (such as 1/2, 2/3, 3/4…) as decimals and percents (3/4= .75, or 75%). Identify place value to trillions. Identify place value of decimals to the thousandths place (.008). “Shade in” a fractional part of a whole and identify the part that is shaded-in as a fraction, a decimal, and a percent of the whole. 25%, .25, 1/4 S H O U L D . . . • Adding and subtracting multi-digit whole numbers and decimals • Multiplying multi-digit whole numbers • Dividing whole numbers • Adding and subtracting fractions with like denominators (1/8 + 3/8) and unlike denominators (1/3 + 3/8) he can use.

Julio has 10-cent stamps, 4-cent stamps, and 2-cent stamps that Use negative numbers in context—on a thermometer, for example. Compare and order fractions and positive and negative numbers (1/3 is less than 1/2, -2 is greater than -10). Solve basic and “extended” multiplication and division facts (if 11x5=55, then 11x50=550; if 10÷5=2, then 100÷50=2). Identify “factors” of a number (numbers that are multiplied to equal a given number). For example, 7 and 3 are factors of 21.

MENTAL ARITHMETIC AND NUMBER SYSTEMS Use and understand the terms “numerator” (the number above the line in a fraction) and “denominator” (the number below the line in a fraction). Fifth Grade 15 MATHEMATICS Use a calculator to rename any fraction as a decimal or a percent. Mentally convert a simple fraction into a decimal or a percent, and vice versa. Use fractions to represent ratios (5 out of 10 students eat breakfast every morning—5/10 or 5:10). Write numbers in different ways, including: • “Standard” notation (3,445) expressing a number as the product of its prime factors (12=2x2x3).

On the first day of the contest, they completed the following numbers of jumps: Lori—41 jumps Jim—45 jumps Peg—33 jumps The graph shows how many jumps the 4 students completed on Day 2 of the contest. A) After 2 days, who had the most total jumps? B) By how many jumps did this student win the contest? C) To prove your answer, show each step of your math work for all 4 students and explain why you solved the problem as you did. If you used mental math or a calculator you must write an explanation describing what you did and also why you solved the problem as you did. Then, write your answer in the boxes below. Will—39 jumps Factor Captor Number Grid Number of Players: 2 Rules: One player chooses a two-digit number on the grid. The other player covers that number’s factors (the numbers that can be multiplied to equal the chosen number) with counters, using each factor only once. Players record the sums of the factors they have covered as their scores for the round. If a player misses any factors, the other player can cover them and add them to his or her total score. They take turns until all numbers on the grid have been covered. Using a calculator, they add their total scores to determine the winner. Example: Shannon covers 27 and writes down “27” as her score for the round. Tiffany covers 1, 3 and 9 with counters (3x9=27; 1x27=27). Her score is 13: 1+3+9. For round two, Tiffany covers 18. Shannon covers 2, 3 and 6. Tiffany then covers 9, because 9 is also a factor of 18, and adds “9” to her score of “18.” 16 What your child should be learning: MATHEMATICS FIFTH GRADE, CONTINUED Draw and measure angles using a protractor.

They make as many bags of trail mix as possible. Answer these questions. Show all of your work or explain how you figured it out. How many bags of trail mix can they make? Which ingredient do they run out of first? How many of the other two ingredients are left over when they are done? In a set of data, find the maximum, the minimum, the median (the middle number of the set), the mode (the number that occurs most often), the range (the difference between the maximum and minimum), and the mean (the average). Use terms that describe the probability of chance events (“It’s likely that it will rain again today”…“It’s unlikely that no student will be absent this year”). 17 Why has math instruction changed? In 1995, the United States and 41 countries around the world participated in the Third International Math and Science Study (TIMSS). Along with testing students at grades four, eight and 12 on their knowledge of math and science topics and their ability to solve problems, TIMSS involved surveying students, teachers and administrators, reviewing the content of curriculum programs and textbooks, and videotaping classroom interactions between teachers and students. When the test results and analyses of data were released, American fourth graders had scores slightly above the international average. Eighth graders’ scores were lower than the international average. Twelfth graders were near the bottom, outscoring only Cyprus and South Africa. We were the only industrialized country to show this decline in performance. TIMSS researchers who studied the data about textbook content, the sequence of courses, and classroom interactions have offered possible explanations for the U.S. results. American schools, they said, approach the teaching of math very differently from many of our international counterparts. For example: • The typical U.S. math curriculum has been called “a mile wide and an inch deep.” In other words, it includes so many topics that few can be covered in depth. • Educators do not agree on what should be taught when, so American students may be taught the same material year after year. For example, basic fraction and decimal facts and operations (adding, subtracting, and so on) are taught from fourth through eighth grade in this country. • As documented in TIMSS videos, some students in American math classrooms are more likely to sit and watch their teachers explain procedures than they are to struggle with math concepts and problem-solving strategies themselves. Everyday Mathematics, which was developed with support from the National Science Foundation and meets the Department of Education’s standards for quality, research- based programs, addresses the challenges posed by TIMSS by providing: • A coherent structure, with math topics introduced in a specific sequence • An emphasis on problem-solving skills, as opposed to asking students to perform essentially the same task over and over • Early introduction of a range of important, higher-level math concepts for all students Note: Southwestern Pennsylvania participated in a similar study in 1999 called the TIMSS-R, or “Repeat.” For information about the results, which are available for the region as a whole but not by individual school or district, go to: www.msc.collaboratives.org.

For more information about the research base for Everyday Math, go to: www.sra4kids.com/everydaylearning/em/ origins.html. 18 GLOSSARY algebraic expression: A way of expressing a quantity that uses a “variable.” For example, Tiffany has five more cookies than Samira. If Samira has c cookies, then Tiffany has c + 5. algorithm: A set of steps that can be used to carry out a procedure—a way of solving a problem. For example, one algorithm for adding 14 plus 23 is to write one number above the other, draw a line underneath, add 4 and 3 which gives you 7, add 10 and 20 which gives you 30, and then add 30 and 7 to get 37. Note: Everyday Math students are encouraged to invent their own algorithms and find strategies that are successful. Teachers also show students “alternative” algorithms, which are additional strategies for performing calculations. For example, K-2 students may add or subtract using a number line or a number chart, by thinking of the quantities as coins, or by using objects. Ask your child’s teacher to show you some of the invented or alternative algorithms being used by the class. area: The measurement of the inside of a given shape. array: An arrangement of real objects or drawn symbols laid out in rows to help children visualize multiplication. For example, to understand three times four, a child might lay out pattern blocks like this: ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ attribute: A feature or characteristic of a group or set of things. For example, a right angle is an “attribute” of squares. fact family: A group of numbers that are “related” like family members by being added together, subtracted, multiplied, or divided. For example, an addition and subtraction “fact family” for 4, 3, 7 would be 3+4=7, 4+3=7, 7-4=3, 7-3=4. frames-and-arrows diagram where the frames are all filled in, but the rule is missing, to discover what rule was used (“What’s My Rule?” problems). In other problems, there are two rules to use, represented by different kinds of arrows, and children are asked to fill in the correct numbers. 2946 Function Machine: A diagram of an imaginary machine that is programmed to process numbers according to a certain rule. The student puts a number into the machine and changes it into a second number by applying the rule. Sometimes the numbers are given and the student must figure out the rule that was applied. See the sample of student work on page 11 for an example. Home Link: The name for the kinds of homework that involve home activities in kindergarten through third grades. Math Box: A box on a worksheet containing a math task. Everyday Math worksheets usually include boxes with different tasks for practicing a variety of skills, rather than one sheet with problems requiring only one skill. Math Message: A brief warm-up activity to begin a lesson. One Math Message: “Take 5 straws and 6 twist-ties. Try to make two triangles with them.” Minute Math: Quick math problems for Kindergarten through third grade that help children develop problemsolving strategies. 5-Minute Math: Fourth and fifth grade math problems, usually given at the beginning of the lesson, that help children develop mental math skills. Name-collection Box: Children use a box diagram to write different names for a number. A “Name-collection Box” for 125 might look like this: (Answer: The rule is +6.) One example of a Frames-and-Arrows diagram 2976 2978 number model: A statement showing that two quantities are equal—an equation. For example, 3+5=6+2. Used in a “number story,” a number model shows how the parts of the story are related. number sentence: A sentence made up of numbers, operations, and a symbol that shows their relationship. For example, 2+2=4, or 327>326, or 5+7=15-3. number story: A word problem made up by children, teachers or parents that describes a situation that can be solved numerically. “Jesse had two pairs of clean socks. After he did his laundry, he had three new clean pairs. How many pairs of clean socks does he have now?” operation: A process or action for combining numbers to produce another number. Addition, subtraction, multiplication, and division are all examples of operations. polygon: A 2-dimensional figure. All the sides are line segments connected end to end. reference frame: Certain kinds of systems for measuring quantities, including number lines, clocks, calendars, thermometers and maps. 100 + 25 $125.00 175 - 50 25 x 5 50 + 50 + 25 fact power: Knowing certain number facts by memory, such as which pairs of numbers add up to 10, or multiplication facts. Frames-and-Arrows: A math diagram that children complete in class or for homework that asks them to complete the “frames”—which may be squares or circles—using a given rule, such as “add five.” The arrows represent the rule used each time. Sometimes children are asked to look at a number grid puzzle: Part of a number grid in which some numbers are missing. Number grid puzzles are used for practicing place value concepts and counting skills. relation symbol: A symbol that shows the relationship between two quantities, such as = (equal to), < (less than), or > (greater than). square number: A number that is the product of a whole number multiplied by itself. For example, 5 “squared,” or 52, is the same as 5x5. number chart or grid: A table in which consecutive numbers are arranged in rows of ten. 2 1 11 12 21 22 31 32 41 42 51 52 61 62 71 72 81 82 91 92 101 102 3 13 23 33 43 53 63 73 83 93 103 4 14 24 34 44 54 64 74 84 94 104 6 5 15 16 25 26 35 36 45 46 55 56 65 66 75 76 85 86 95 96 105 106 Number chart or grid 8 7 18 17 28 27 38 37 48 47 58 57 68 67 78 77 88 87 98 97 107 108 9 19 29 39 49 59 69 79 89 99 109 0 10 20 30 40 50 60 70 80 90 100 110 Study Link: The name for some kinds of homework in fourth and fifth grades. tally mark: A vertical mark used to keep track of the number of items in a group. Typically they are grouped by fives, to make it easy to determine the final amount. The fifth line is a cross-stroke. |||| || unit and unit box: The item or object being counted or measured is the unit. (In the problem, “Twelve cows in a field walked into another field where two cows were grazing. How many cows in all?” the unit is cows.) Children may be asked to write or draw in a “unit box” to show the unit being used. Using a unit with a number reinforces the idea that numbers refer to something.
