Combining Like Terms: Using the Commutative and Associative Properties

This lesson teaches how to combine like terms using the commutative and associative properties. The commutative property allows terms to switch places, while the associative property allows grouping of terms without changing the result. Through examples involving cookies and boxes, students learn to identify and combine like terms, ensuring only similar items are added together. The lesson emphasizes understanding these properties to simplify expressions and solve problems effectively.
