## Reflection: Developing a Conceptual Understanding Partition & Measurement Models - Section 1: Warm Up

A clear and specific focus on the structure of the division sentence is critical for developing students' understanding of this concept.  Understanding that the dividend represents the whole amount, the divisor represents the items in a group, and the quotient represents the number of groups should not be skipped over.  Understanding this structure will help students determine the type of model that can be used to solve.

It is also important to discuss what "remainders" represent. When students encounter remainders, they need to understand that the remainder represents less than a whole group rather than less of an item.

For example 7  ÷ 2 = 3 remainder 1.  If the context is houses, there is one house that is not part of a whole group of two.  It is not possible to share the house equally among the three groups.  Understanding this concept is crucial to understanding division.
