Unit of Instruction  Focus 3: Ratio, Proportion & Percent 

Standard(s) Taught 

MAFS.7.RP.1.2
Recognize and represent proportional relationships between quantities.

Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin.

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

Represent proportional relationships by equations.

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.

Learning Targets and Learning Criteria 

Students are successful when they can…
 compute a unit rate by iterating (repeating) or partitioning given rate.
 compute a unit rate by multiplying or dividing both quantities by the same factor.
 explain the relationship between using composed units and a multiplicative comparison to express a unit rate.
 use measures of lengths and areas to calculate unit rates with the given context.
 analyze ratios in a table to determine if the ratios are equivalent by finding the constant of proportionality.
 calculate the cross product to determine if the two ratios are in proportion (equivalent).
