Topics
- Ratios
- Proportional Reasoning
- Double Number Line
- Unit Rate
Sample Learning Goals
- Interpret ratios of mixed units (e.g. $/lb)
- Define the unit rate and determine a method to calculate it
- Predict how changing the numerator or denominator of a rate will affect the unit rate
- Use the double number line to reason about rates and solve real-world problems
- Develop strategies to use the unit rate to solve problems
- Compare unit rates between two simultaneous situations

6.RP.A.3d
Use ratio reasoning to convert measurement units; manipulate and transform units appropriately when multiplying or dividing quantities.6.RP.A.3b
Solve unit rate problems including those involving unit pricing and constant speed. For example, if it took 7 hours to mow 4 lawns, then at that rate, how many lawns could be mowed in 35 hours? At what rate were lawns being mowed?6.RP.A.3
Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.6.RP.A.2
Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio relationship. For example, “This recipe has a ratio of 3 cups of flour to 4 cups of sugar, so there is 3/4 cup of flour for each cup of sugar.” “We paid $75 for 15 hamburgers, which is a rate of $5 per hamburger.”1
