About this worksheet

What students practice

  • Students graph proportional relationships using tables and unit rates.
  • Students interpret slope as the unit rate of a proportional relationship.
  • Students compare proportional relationships represented in different ways.

How to use

Use after introducing proportional graphs. Have students label axes and show rate calculations, then discuss why totals alone cannot determine the faster rate.

Curriculum

Common Core standard covered

8.EE.B.5

Graph proportional relationships, read the unit rate as the slope, and compare two proportional relationships shown in different ways.
