This lesson focuses on applying the associative and commutative properties to simplify and solve multiplication problems. Students will learn to apply these properties to support them in solving multiplication problems more efficiently and with greater ease. Students will:

- apply the associative and commutative properties to simplify and solve multiplication problems.

How are relationships represented mathematically?

How can expressions, equations, and inequalities be used to quantify, solve, model, and/or analyze mathematical situations?

How can mathematics support effective communication?

How is mathematics used to quantify, compare, represent, and model numbers?

**Division:**The mathematical operation of splitting a quantity into equal groups. (For example, 8 ÷ 2 = 4 because splitting 8 into 2 equal groups results in 2 groups of 4.)**Equation:**A statement of equality between two mathematical expressions.**Factor:**A number that is multiplied with another number to form a product.
