Algebraic Expressions
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.
Write a variable expression for each model. Squares represent ones. Rectangles represent a variable.

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