Grade 6: Ratios and Proportional Relationships

6.RP.A

Understand ratio concepts and use ratio reasoning to solve problems.

6.RP.A.1

Fully covered
Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.

6.RP.A.2

Fully covered
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.

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.3.a

Fully covered
Make tables of equivalent ratios 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.A.3.b

Fully covered
Solve unit rate problems including those involving unit pricing and constant speed.

6.RP.A.3.c

Fully covered
Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent.

6.RP.A.3.d

Fully covered
Use ratio reasoning to convert measurement units; manipulate and transform units appropriately when multiplying or dividing quantities.
