## Where Did the Parentheses Go

#### Activity Overview

In this activity, students use the order of operations and number properties to create a unique expression from a set of numbers that must equal another number. Then, they will place parenthesis in a number statement to make it true. Students will also identify properties commonly used to evaluate expressions.

#### Key Steps

• In this activity, students use the order of operations and number properties to create a unique expression from a set of numbers that must equal a given number. They will also determine how to correct an expression that does not equal that number.

• Students also explore the placement of parentheses to ensure number sentences evaluate correctly. Finally, students use the Commutative or Associative Properties of Addition and Multiplication to complete equations.
