### Lesson Purpose

The purpose of this lesson is for students to divide decimals greater than 1 by decimals less than 1.

### Lesson Narrative

In previous lessons, students divided whole numbers by decimals and decimals by whole numbers, with the decimals always less than 1. The purpose of this lesson is for students to apply their understanding of the number of tenths and hundredths in 1 whole to divide a decimal greater than 1 by a decimal. Students use the same strategies that they have in previous lessons to find these quotients
