Form was emphasized:
(1) Set up the problem including the original expression and values for the variables
(2) Substitute values for the variables
(3) Solve
Guided practice given to review how to evaluate algebraic expressions. Students solved for distance, perimeter, volume, and the number of diagonals for a polygon using formulas and given values. See examples below. Finish for homework and show work as demonstrated.

1. 10x  20y
2. 9y + 6x 3. 4a + 3b + c 4. x + x  x + y + y = x + 2y ***The solution given, 2x + 2y, is not correct. In order for the two expressions to be equivalent, you would have to do one of the three things: (1) remove  x from the first expression (2) add x to the first expression (3) change the expression 2x + 2y to x + 2y 3(x + 2y) = 3x + 6y 3x + x + y + 2y = 4x + 3y

1. 12x + 6y
2. 16y  12x 3. 2f + 2e 4. x + y  x + y  y = y Rearrange the terms using the commutative property to find zero pairs: x  x = 0 , y  y = 0 . The only term left is a single y. 2(3x  y) = 6x  2y Distribute. 2(x + 2y)  3y = 2x + 4y  3y First distribute. Then, simplify by combining like terms. 4y  3y = 1y. Therefore, what's left is 2x + y.
