4. Circle Pieces
Practice alone on the pages labeled “Circle Pieces 1 – Circle Pieces 3.” This will enforce the idea of representing fractions in both words and symbols.
Why is that important?

5. Pizza Pieces
Elbow Partners: work together with the fraction circles to complete the pages “Pizza Pieces 1 – Pizza Pieces 2.” We will discuss #3 to see if Fran is full.

6. Pizza Problems 1
Elbow Partners: work together to solve each problem. Describe how you solved each, and then write a number sentence that goes with it. We will share out.

Mom just filled the cookie jar with cookies. They were chocolate-chunk cookies – my favorite. My brother came home from soccer practice and took half the cookies. My sister came home from dance lessons and took half of what was left. When my dad got home from work, he took half the remaining cookies. By the time I finished my homework and went downstairs for a snack, there were only two cookies left. How many cookies did mom put in the cookie jar?
There were 16 cookies in the cookie jar.
