About the Mathematics in This Unit

Benchmarks/Goals	Examples
Use the order of operations to solve computation problems.	How can you use parentheses and brackets to make this equation true? 14 − 3 + 2 ÷ 3 = 3 [14 − (3 + 2)] ÷ 3 = 3 [14 − 5] ÷ 3 = 3 9 ÷ 3 = 3

Benchmarks/Goals

Examples

Use the order of operations to solve computation problems.

How can you use parentheses and brackets to make this equation true?

14 − 3 + 2 ÷ 3 = 3

[14 − (3 + 2)] ÷ 3 = 3

[14 − 5] ÷ 3 = 3

9 ÷ 3 = 3

In our math class, students spend time discussing problems in depth and are asked to share their reasoning and solutions. It is most important that children accurately and efficiently solve math problems in ways that make sense to them. At home, encourage your child to explain his or her math thinking to you. Please look for more information and activities about Puzzles, Clusters, and Towers that will be sent home over the next few days.
