Learning Material  |  Interactive Lesson  |  RAR

Published on 2014 April 29th

Test your understanding of ratios by choosing two gears of different sizes according to specific criteria. Complete a pair of gears, or choose the combination of two gears, depending on how many rotations each gear must make. For example, choose a belt gear size of 10 teeth and a driver of 40 teeth to make the belt gear rotate 4 times for every 1 rotation of the driver. This assessment object is one in a series of two objects.
Students demonstrate multiplicative thinking strategies to interpret situations and solve problems involving ratios.
