Modeling division is necessary for students to understand the concept behind the division algorithm. Once they understand why each step of the process is performed, they will have greater success in mastering the algorithm.

**Materials:** base-ten blocks (1 hundred, 12 tens, and 24 ones)

**Preparation:** Provide at least one set of base-ten blocks for each pair of students.

**Prerequisite Skills and Concepts:** Students must have a basic understanding of division, and they must know the basic division facts.
