This activity is a matching game, for students to play when practicing simplifying square roots. There are 32 cards total, making for 16 matches. For your clarification, the square roots that need to be simplified have been shaded purple, while the simplified expressions have been shaded red. When making copies of this game for your class, I recommend copying the two different types of cards on different colored paper or card stock. This way, the students know to turn over one of each color card when looking for a match. To play, the students lay all of the cards out face down, and then take turns looking for matches. On each turn a student should flip over two cards, one of each type. All students playing should simplify the square root, to check one another's work, and compare the simplified expression to the other card that was flipped over. If a match is found, the student who flipped the cards over gets to keep the match and go again. If not, the cards are flipped back over and play continues. The student with the most matches at the end of the game is the "winner"!
