Apply the properties of operations to generate equivalent expressions. For example, apply the distributive property to the expression 3(2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6 (4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y.

This lesson really applies math practice standard five (MP5)by allowing students to use area models to visualize and understand the distributive property through illustration. In closing the lesson you can begin to move students into more abstract and algebraic expressions if you feel they are ready, such as (3x +4y)²
