Meeting Common Core State Standards This Really Good Stuff® EZ Stick Write Again® Table Toppers – Number Lines is aligned with the following Common Core State Standards for Mathematics: Counting and Cardinality K.CC.A.2 Count forward beginning from a given number within the known sequence (instead of having to begin at 1). K.CC.A.3 Write numbers from 0 to 20. Represent a number of objects with a written numeral 0–20 (with 0 representing a count of no objects). Compare Numbers K.CC.C.7 Compare two numbers between 1 and 10 presented as written numerals. Operations and Algebraic Thinking K.OA.A.1 Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations. K.OA.A.2 Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem. 1.OA.A.1 Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to present the problem. Measurement and Data 2.MD.B.6 Represent whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, . . . . Displaying the EZ Stick Write Again® Table Toppers – Number Lines Before removing the EZ Stick Write Again® Table Toppers – Number Lines from their protective backing, make copies of this Really Good Stuff® Activity Guide and file the pages for future use. Or, download another copy of it from our Web site at www.reallygoodstuff.com. Select a table to use for small group instruction. Remove each Number Line from the protective backing, gently press it to the desired location, and smooth it flat. Place a basket with dry erase markers and erasers on the table for easy access. Save the protective backing sheets to store the Number Lines. When you are ready to store the Number Lines, gently peel them from the table, and reposition them on the backing sheets. Always use a dry erase marker on the Number Lines to preserve their Write Again® wipe-off laminate surface. Introducing the EZ Stick Write Again® Table Toppers – Number Lines Gather students around the table with the EZ Stick Write Again® Table Toppers – Number Lines. Tell them that number lines are tools that will help them visualize numbers, and explain that these Number Lines show the numbers from 0 to 20. Ask students how frogs move, then point to the frog on the Number Line. Demonstrate how you can hop up the Number Line like the frog by moving your finger from number to number as you count to 20. Select a group of students to work at the table with the Number Lines. Have them use the Number Lines to count, compare numbers, add and subtract, and find missing numbers. Emphasize that students should only use dry erase markers on the Number Lines, and that they should erase the Number Lines at the end of the activity. Order of Numbers For young students, use the Number Lines to help them count from 0 to 20. Have students use their dry erase markers to make hops from 0 to 20 as the group counts together. Next, have students count forward from a given number on the Number Line. For a challenge, have students count backward from 20 to 0, making hops as they say each number. Comparing Numbers Prepare two sets of index cards with the numbers from 0 to 10. Shuffle each set of cards. Have students choose two cards and then locate each number on the Number Line. Ask students to say a number sentence with the two numbers using the terms greater than, less than, or equal to. Extension: Have students write a number sentence with <, >, or =. Adding Model solving 5 + 7 by locating the number 5 on the Number Line and then making 7 hops up the Number Line to the number 12. Circle the number 12. Have students explain how the picture and number sentence match. Give students the opportunity to solve additional problems. Subtracting Model solving 13 – 6 by locating the number 13 on the Number Line and then making 6 hops down the Number Line to the number 7. Circle the number 7. Have students explain how the picture and number sentence match. Give students the opportunity to solve additional problems. Missing Numbers Display the problem 6 + ? = 11. Think aloud: 6 plus something equals 11. We need to figure out how many hops will get us from 6 to 11. Find the number 6 on the number line, and let’s all hop 1, 2, 3, 4, 5 times to get to 11, so now we know that 6 + 5 = 11. Have students use the Number Lines to solve additional missing number problems. Addition and Subtraction Practice Copy and distribute the Addition and Subtraction Reproducible. Remind students to look for key words in word problems to help them know whether to add or subtract and review possible key words with them. Have students complete the problems independently, in small groups, or as homework. You may wish to use the reproducibles for assessment. Answers: 1) 11, 2) 8, 3) 17, 4) 6, 5) 15, 6) 7, 7) 12, 8) 9 All activity guides can be found online.
