Grade 7: Proportional Reasoning

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

7.1

Fully covered
Calculate unit rates of length, area, and other quantities measured in like or different units that include ratios or fractions.

7.2

Represent a relationship between two quantities and determine whether the two quantities are related proportionally.

7.2.a

Fully covered
Use equivalent ratios displayed in a table or in a graph of the relationship in the coordinate plane to determine whether a relationship between two quantities is proportional.

7.2.b

Fully covered
Identify the constant of proportionality (unit rate) and express the proportional relationship using multiple representations including tables, graphs, equations, diagrams, and verbal descriptions.

7.2.c

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

7.3

Fully covered
Solve multi-step percent problems in context using proportional reasoning, including simple interest, tax, gratuities, commissions, fees, markups and markdowns, percent increase, and percent decrease.
