**Measurement Division Tool.** The Measurement Division tool allows you to model division, and then show how division can be used to find how many equal-sized groups are contained in a starting amount. The tool uses the phrase “contains…groups of,” as in “40 contains 4 groups of 10.” Then it allows the transition from this phrase to using the equation, and numbers-only.

Explore two lessons from our breakthrough fractions curriculum. Each lesson uses visual models to develop students' thinking as it progresses from concrete to abstract representations.
