Recipes

• I can explain what it means for two ratios to be equivalent using a recipe as an example.
• I can use a diagram to represent a recipe and to represent a double batch and a triple batch of the recipe.
• I know what it means to double or triple a recipe.

Color Mixtures

• I can explain the meaning of equivalent ratios using a color mixture as an example.
• I can use a diagram to represent a single batch, a double batch, and a triple batch of a color mixture.
• I know what it means to double or triple a color mixture.

Defining Equivalent Ratios

• If I have a ratio, I can create a new ratio that is equivalent to it.
• If I have two ratios, I can decide whether they are equivalent to each other.

Introducing Double Number Line Diagrams

• I can label a double number line diagram to represent batches of a recipe or color mixture.
• When I have a double number line that represents a situation, I can explain what it means.

Creating Double Number Line Diagrams

• I can create a double number line diagram and correctly place and label tick marks to represent equivalent ratios.
• I can explain what the word "per" means.

How Much for One?

• I can choose and create diagrams to help me reason about prices.
• I can explain what the phrase “at this rate” means, using prices as an example.
• If I know the price of multiple things, I can find the price per thing.

Constant Speed

Representing Ratios with Tables

• If I am looking at a table of values, I know where the rows are and where the columns are.
• When I see a table representing a set of equivalent ratios, I can come up with numbers to make a new row.
• When I see a table representing a set of equivalent ratios, I can explain what the numbers mean.

Navigating a Table of Equivalent Ratios

• I can solve problems about situations happening at the same rate by using a table and finding a “1” row.
• I can use a table of equivalent ratios to solve problems about unit price.

Tables and Double Number Line Diagrams

• I can create a table that represents a set of equivalent ratios.
• I can explain why sometimes a table is easier to use than a double number line to solve problems involving equivalent ratios.
• I include column labels when I create a table, so that the meaning of the numbers is clear.
