Run off the entire sets and laminate. I file mine in file folders so that have easy access to our weekly words. I would keep a 10 - 15 word pairs in a bin. Make sure the words you have already covered and your weekly words are included. Then have students turn them all over. Take turns finding matching pairs. Winner is the one who has the most pairs by the end of the game. Just another way to have students immersed in word work that keeps it fun.
Thanks so much! Nina
