I can create tape diagrams to help me reason about problems that involve both a ratio and a total amount.
I can solve problems when I know a ratio and a total amount.
16
I can choose and create diagrams to help think through my solution.
I can solve all kinds of problems about equivalent ratios.
I can use diagrams to help someone else understand why my solution makes sense.
6
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.
7
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.
8
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.
9
I can choose and create diagrams to help me reason about constant speed.
If I know that an object is moving at a constant speed, and I know two of these things: the distance it travels, the amount of time it takes, and its speed, I can find the other thing.
10
I can decide whether or not two situations are happening at the same rate.
I can explain what it means when two situations happen at the same rate.
I know some examples of situations where things can happen at the same rate.
17
I can apply what I have learned about ratios and rates to solve a more complicated problem.
I can decide what information I need to know to be able to solve a real-world problem about ratios and rates.
11
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.
12
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.
13
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.
14
I can decide what information I need to know to be able to solve problems about situations happening at the same rate.
I can explain my reasoning using diagrams that I choose.
