Grade 6 Go Math! Quarterly Planner 12 Days CHAPTER 4 Ratios and Rates BIG IDEA: In 6th grade, students are introduced to ratios, rates, and unit rates. Students need to shift their thinking from reasoning on a single quantity (as with a fraction), to reasoning about two quantities. A frequent misconception among students is that a ratio is just another name for a fraction. Students with conceptual understanding of a ratio recognize a number of mathematical connections that link ratios and fractions. In reference to rates and unit rates, discussing rate as a set of infinitely many equivalent rations, “can support students in developing deeper understanding of the concept” (Lobato, Ellis, Charles, & Zbiek, 2010). This interpretation of rate also supports students’ use of the concept in upper level mathematics courses and is a key aspect of proportional reasoning.

How do you write ratios and rates? How can you use a multiplication table to find equivalent ratios? Math Content and Strategies Apply what students already know about multiplication to ratio relationships. For example, if students show the ratio 2 adults for every 3 students with their counters, they can also show how many students there would be if there were 4 adults. Make sure to point out the red counters were multiplied by 2 and the yellow counters were also multiplied by 2. The two ratios, 2:3 and 4:6, name the same comparison. Rates are ratios that compare two quantities that have different units of measure. In a unit rate, the second quantity is always 1. Discuss unit rates such as cost per pound of fruit, or cost per gallon of gas. Converting between rate and unit rate can help when comparing prices of multiple items Using a table can help students see the multiplicative relationship among equivalent ratios. -Suppose that there are 3 erasers for every 4 pencils.

How can you use table to solve problems involving equivalent ratios? How can you use unit rates to make comparisons? How can you solve problems using unit rates? Use two tables to compare two ratios and determine if the ratios are equivalent. As the students work with tables, point out that each number pair in a column can also be written in fraction form. If the same number appears in either the top or bottom row in the two tables, students can compare the ratios in those columns to determine if the other term is also the same. Students can also compare ratios by writing ratios in simplest form. Use ratio reasoning to solve real-world problems. Help students make connections between what they are learning and a real-life situations, such as planning a class party. Two jars of punch are enough for 12 people. If you expect 36 people at your class party, how can you find the number of jars of punch you will need to buy? How many jars will you need? How many jars of punch would you need for 34 people? When students can find unit rates, it allows them to easily compare rates, such as comparing prices in order to save money. A 14 oz. bottle of syrup costs $3.64. A 17 oz. bottle of syrup costs $4.25. Which one is the better buy? Using unit rates will allow students to compare the prices per ounce to determine the better buy. In this lesson, students are introduced to using unit rates to solve problems. One approach is to model the known ratio as a unit rate. For Ratio Tables Fernando donates $2 to a local charity organization for every $15 he earns. Cleo donates $4 for every $17 she earns.

He claims that he can type a 500-word essay in 5 minutes. Does Emilio's claim make sense or not? Use a graph to help explain your answer. Students can find the unit rate by finding a ratio with a denominator of 1. They can make a table of equivalent ratios for the known points and use the pattern to extend the table to include a ratio with a denominator of 1. Students can also find the unit rate by finding the ordered pair where the x-coordinate is equal to 1. They can use the multiplicative relationship between the x-coordinates and y-coordinates of the ordered pairs of known points to find the unit rate. *Plot the unit rate, then use plot the equivalent ratios to solve.

Quarterly Planner 9-11 Days CHAPTER 5 Percents BIG IDEA: In 6th grade, students learn about percents and how they are connected to ratios. A percent is a special ratio that compares a number to 100. Students gain understanding of percent by comparing and making connections among the various forms in which a percent may be represented, including ratios, fractions, and decimals (Reys, 2001). “Ideally, all of these ideas (fractions, decimals, ratio, proportion, and percent) should be conceptually integrated. The better that students connect these ideas, the more flexible and useful their reasoning and problem solving skills will be.” (Van de Walle, 2004) ESSENTIAL QUESTION: How can you use ratio reasoning to solve percent problems?

Using models to introduce percent allows students to develop a concrete understanding of percent as the relationship between part and whole. A deeper understanding of percents allows students to see a percent as another way to express equivalent numbers. Convert percents to fractions and decimals. This lesson reinforces the idea that percents, fractions, and decimals are all different ways to express the same numerical value. Students should understand that 100% represents one whole or the total, converting percents to equivalent benchmarks and relating these concepts to situations students are familiar with.

Quarterly Planner 8-9 Days CHAPTER 6 Units of Measure BIG IDEA: In 6th grade, students are learning how to convert from one unit of measurement to another. Many times, students struggle with knowing whether to multiply or divide when they need to convert from one unit of measure to another. They should think about the relationship of the units. Questions such as, “How are the units related-what is the relationship or formula?” or “Is the unit being converted smaller or larger than the target unit?” will be helpful for the students in determining which operation they should use. The focus of the unit must be on reasoning rather than on determining whether to divide or multiply. “Mathematically proficient students… continuously ask themselves, ‘does this make sense?’” (NGA Center/CCSSO, 2010) ESSENTIAL QUESTION: How can you use measurements to help you describe and compare objects?

How can you use ratio reasoning to convert from one unit of capacity to another? How can you use ratio reasoning to convert from one unit of weight or mass to another? How can you transform units to solve problems? Math Content and Strategies Use a conversion factor or conversion chart (metric system) to convert from one unit of length to another. A chart is simple to use because the metric system is based on powers of 10, once again emphasizing the importance of place value. Use a conversion factor or conversion chart (metric system) to convert from one unit of capacity to another. It is important that students learn about the customary system of measurement used in the United States, as well as the metric system of measurement, the system used in most other countries. Converting customary units reinforces students’ understanding of rates and equivalent rates. Use a conversion factor or conversion chart (metric system) to convert from one unit of weight or mass to another.

Quarterly Planner 12-13 Days CHAPTER 7 Algebra: Expressions BIG IDEA: In 6th grade, students begin to work with expressions and equations with variables. Research indicates that students have difficulty understanding the nature of variables. It’s crucial that teachers communicate that there are three common uses for variables in math: a) Variables can represent a specific unknown (Ex. x + 5 = 12) b) Variables can be used as a pattern generalizer (Ex. a + b = b + a) c) Variables are used as quantities that vary in joint variation (Ex. y = 2x + 3, as x changes, so does y). When simplifying expressions with algebraic expressions, students have a tendency to add unlike terms due to students’ desire to find a “final result.” To avoid this, try attaching visual are other concrete meaning to algebraic terms or modeling authentic problems.
