1. 7.RP.2: Recognize and represent proportional relationships between quantities.
7.RP.2b: Identify the constant proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.
I can find unit rates at least at 80% proficiency.

2. Vocabulary
Rate: A ratio that compares to quantities with different kinds of units.
Unit Rate: when a rate is simplified so that the denominator is 1.
