Eureka Math

3rd Grade

Module 1

Lesson 13

At the request of elementary teachers, a team of Bethel & Sumner educators met as a committee to create Eureka slideshow presentations. These presentations are not meant as a script, nor are they required to be used. Please customize as needed. Thank you to the many educators who contributed to this project!

​

Directions for customizing presentations are available on the next slide.

Lesson Objective:Interpret the quotient as the number of groups or the number of objects in each group using units of 3.

~Describe how the model in 2(a) helped for drawing a tape diagram?

~How does the Application Problem connect the work we did yesterday to what we did today?

~Share work for Problem 5. The language some friends rather than a number may have presented a challenge.

~Compare Problems 4 and 5. How did your approach to drawing the tape diagram change? Why?
