Objectives I will model algebraic expressions. I will replace a variable with a given value and then evaluate the answer. I will use the distributive property to rewrite an expression and simplify.

Write a variable expression for each model. Squares represent ones(1) Write a variable expression for each model. Squares represent ones(1). Rectangles represent a variable (x). 2. 1. 3.

SPI 0606.1.5 Model algebraic expressions using algebra tiles.

SPI 0606.1.5 Model algebraic expressions using algebra tiles.

Write an algebraic expression to represent this model. Answer: -3x +5

Evaluate each algebraic expression 3m; where m = 9 4y + 6; where y = 6 2 (4e); where e = 5 3pq; where p=3 and q = 5 7n – (m + 18); where n = 4 and m = 10

Simplify each expression by combining like terms and complete all operations. 2m + 8 + 12 +5m 5(2m • 2) + 8m

SPI 0606.3.4 Rewrite expressions to represent quantities in different ways.

Simplify this expression and write the operations that were performed in each step. 4 (m + 8) + 5m

Simplify this expression and write the operations that were performed in each step. 4² (6n – 3n) + 85

Create your own expression for your partner to model/evaluate Create your own expression for your partner to model/evaluate. The partners will have to model it correctly and write the operation that was performed.

Today You have learned how to evaluate and model algebraic expressions . You have reviewed, modeled, evaluated, and simplified expressions using the distributive model. You have used algebra tiles to model algebraic expressions. Give yourself a pat on the back!
