Combining Like Terms Sorting Cards

It's time to share another resource.  This card sort was modeled off of one that Sarah Carter shared on her blog here for solving equations with variables on both sides.  I had been looking for an activity to have my students practice combining like terms, but a lot of what I was finding was very simple expressions like 2n + 3n.  I created this card sort so that students would get practice combining like terms with expressions that have different variables and exponents.

This card sort contains 12 cards.  Students sort the cards into 3 groups of 4 cards so that all four cards in each group simplify to the same expression.  An answer key is included.
