Grade 7: Ratios and Proportional Relationships

Cluster: Analyze proportional relationships and use them to solve real-world and mathematical problems.

7.RP.1

Fully covered
Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. (MP.2, MP.6)

7.RP.2

Recognize and represent proportional relationships between quantities. (MP.1, MP.2, MP.3)

7.RP.2.a

Fully covered
Decide whether two quantities represent a proportional relationship.

7.RP.2.b

Fully covered
Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams and verbal descriptions of proportional relationships.

7.RP.2.c

Fully covered
Represent proportional relationships by equations.

7.RP.2.d

Fully covered
Explain what a point (x, y) on the graph of a proportional relationship means in terms of the situation, with special attention to the points (0, 0) and (1, r) where r is the unit rate.

7.RP.3

Use percents to solve mathematical and real-world problems. (MP.5, MP.6)

7.RP.3.a

Fully covered
Find a percent of a quantity as a rate per 100; solve problems involving finding the whole, a part and a percent, given two of these.

7.RP.3.b

Fully covered
Use proportional relationships to solve multistep ratio and percent problems.
