Task# Walk-a-thon 1

Illustrative MathematicsVaries

In this task, students are given information about a context where there is a proportional relationship between two quantities in a table that has missing values. Students need to fill in the missing values, plot the corresponding points in the coordinate plane, and find the two unit rates that are associated with this proportional relationship. They then use these mathematical tools to make predictions about the future. In 7th grade, students will deepen their understanding of the connections between tables, graphs, and verbal descriptions that represent proportional relationships and identify the unit rate as the vertical coordinate of a point on the graph with horizontal coordinate 1.
