Show Me The Numbers 
Copy each expression below onto an index card. Shuffle the cards and lay them face down in a stack on the table. Let one of the number cubes represent your xvalue and the other number cube represent your yvalue.
Expressions to put on cards: 
xy
4y  3
5x + y 
x + y
x + y  6
x  y 
2x  2y
2x + 3y  2
5x  3y 
3x + 2
x  2y + 4
3x + y + 3 
Player 1 begins by turning the top card over and rolling the number cubes. Both players use their scratch paper to evaluate the expression if x equals the value on the x number cube and y equals the value on the y number cube. Next, as a group, use your graphing calculator to check the answer. You receive 1 point for each correct answer. Play until all the cards have been used.
