1st Grade

Module 2

Lesson 7

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.

Concept Development

Let’s read this story problem:

Peter has 8 books, and Willie has 5. How many books do they have altogether?

​

What are the different ways we can solve

8 + 5?

44 of 89

Concept Development

I heard some of you say these suggestions: Count on! Make ten with 5! Make ten with 8!

45 of 89

Concept Development

Let’s use the last strategy to solve 8 + 5. Everyone, make ten with 8.
