1. Algebraic Expressions

2. Objectives I will model algebraic expressions with popsicle stick and cubes. I will replace a variable with a given value and then evaluate the answer.

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

4. SPI 0606.1.5 Model algebraic expressions using algebra tiles. Write an algebraic expression for this model and write the operations performed in each step.

5. Evaluate each algebraic expression 1. 3m; where m = 9 2. 4y + 6; where y = 6 3. 2 (4e); where e = 5

6. Evaluate each algebraic expression 4.3pq; where p=3 and q = 5 5.7n – (m + 18); where n = 4 and m = 10 6.5(6 2) + 8m; where m = 2

7. 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.
