Task

Comparing Growth, Variation 1

Illustrative MathematicsVaries

The purpose of this task is to foster a classroom discussion that will highlight the difference between multiplicative and additive reasoning. Some students will argue that they grew the same amount (an example of 'additive thinking'). Students who are studying multiplicative comparison problems might argue that Jewel grew more since it grew more with respect to its original length (an example of 'multiplicative thinking'). This would set the stage for a comparison of the two perspectives.
