About this worksheet

What students practice

  • Students decide whether table values have equal ratios.
  • Students test whether graphed quantities lie on a straight line through the origin.
  • Students distinguish proportional rating gains from nonproportional total ratings.

How to use

Have students mark ratio evidence beside tables and check both graph conditions. Discuss the final explanation after independent work.
