It is difficult to show a use for multiplying fractions that seems both fun and real. In this activity, students learn about a "multi-ray" which changes the size of an object. When the multi-ray is set to more than 1, it is enlarged. When it is set to between 0 and 1, it is made smaller. This activity starts by teaching the concept of scaling by whole numbers, then scales a whole number by a fraction, then a fraction by a whole number, and finally a fraction by a fraction. This activity includes a "constructed response" section where students compare each part of the activity. This product now includes "Multi-Rays" for you and your students to use to practice growing and shrinking using fractions!
