For this activity, each group (2-4 students) gets one set of cards. They set them up in a rectangle with the words faced down. Students take turns flipping over 2 cards at a time. If they get a match (English and Spanish translation) they keep the cards and take another turn. When all cards are gone, the student with the most pairs is the winner.
I print these on card stock so that they last, and have students cut them out.
