Grade 7 Mathematics Module 1, Topic B, Overview

Studying for Test

In Topic B, students learn that the unit rate of a collection of equivalent ratios is called the constant of proportionality and can be used to represent proportional relationships with equations of the form y = kx, where k is the constant of proportionality (7.RP.2b, 7.RP.2c, 7.EE.4a).  Students relate the equation of a proportional relationship to ratio tables and to graphs and interpret the points on the graph within the context of the situation (7.RP.2d).
