Lesson Purpose

The purpose of this lesson is for students to make sense of base-ten representations for division.

Lesson Narrative

In the previous lesson, students applied their understanding from grade 3 to divide two- and three-

digit numbers by one-digit divisors. Students worked with dividends slightly beyond 100 and

represented their thinking in a way that made sense to them.

In this lesson, students work with larger dividends and represent problems with base-ten blocks.

This representation emphasizes place value, which supports the work with division in this section.

Students are asked to represent their work with base-ten blocks on paper, but that is not the

emphasis of this lesson. In the next lesson, students will make sense of and use base-ten diagrams.

In future lessons, they will be able to choose a representation and method that makes sense to

them as they go deeper into division work.

Learning Goals
