The assessment is aligned to the Common Core State Standards for Mathematics – Grade 6 – Ratio and Proportional Relationships
6.RP.1 Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.
6.RP.2 Understand the concept of a unit rate a/b associated with a ration a:b with b 0, and use rate language in the context of a ratio relationship.
6.RP.3 Use ratio and rate reasoning to solve real world and mathematical problems.
6.RP.3a Make tables of equivalent ratio relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios.
6.RP.3b Solve unit rate problems, including those involving unit pricing and constant speed.
6.RP.3c Find a percent of a quantity as a rate per 100; solve problems involving finding the whole, given a part and the percent.
6.RP.3d Use ratio reasoning to convert measurement units; manipulate and transform units appropriately when multiplying or dividing quantities.

1. Write a ratio to show the relationship between 4 wheels on a car and 1 steering wheel in a car. Provide the three different ways the ratio can be written.
2. Write a description and an explanation for the ratio of 7 red blocks to 5 blue blocks.
3. A package containing 5 neon markers cost $4.95. What is the cost of one marker?
4. A package containing 12 highlighters cost $4.80. What is the cost of one highlighter?

1. 4 to 1, 4:1, 4/1
2. The ratio of red blocks to blue blocks is 7:5, because for every 7 red blocks there are 5 blue blocks.
5. Emily paid $3.60 for 24 mechanical pencils, so $0.15 was the cost of 1 mechanical pencil.
