Lesson 16

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.

Problem Set

Debrief

How could you use a tape diagram to solve Problem 1? Which strategy did you use to solve? Could you have used a different simplifying strategy?

Which operation did you choose to solve Problem 2? Why? How does a tape diagram help you to show the situation?

How did you show your thinking in Problem 3? What simplifying strategy can you use to solve? Why choose that one?

Debrief

Explain to your partner the steps you took to solve Problem 4. How did you represent this multi-step problem? What simplifying strategy did you use instead of unbundling a ten for the first portion of the problem?

For Problem 5,share your drawings with a partner. What did you need to know before you could figure out how many books were in the yellow bin? How did you show it?
