Well, this is a very simple worksheet: first, print it and cut the squares. In class, have students work in pairs or groups. Each pair/group gets one stack of cards and they should shuffle the cards and place them facing down. And you know how memory games go...they take turns, choose two cards, turn them around to see if the match, etc. I have them say the words aloud as they pick the cards so that they practice and I can check pronunciation. Enjoy!
