This is a simple math center for Pearson topic 3.9, solving for algebraic expressions and inequalities. There are 8 expressions and 8 values for x. All of the cards are placed upside down, and two are drawn. If it is an expression and a value for x that works in that expression (eg "2x=6" and "x=6"), the student keeps them as a match. If the cards don't match, they are put back where they were and the next student goes.
It is all on one page, which makes prep easier! I printed 4 sets, but did each on a different color paper to keep sets straight.
Can be used for groups of 1 - 3 students.
