Are you teaching a "definition" too? If so, write each word on a separate index card and each definition on a separate card. Pass them out, then the kids to could "walk around" and find their partner/match. If you don't use definitions, you could find a representative picture (or even have the kids draw one as part of the introduction to the new words part of the lesson), then they could match the words to the pictures. I say representative pictures because words that are verbs are often harder to find pictures for than nouns. Some explanation may be required of how the picture relates to the word. It's all about context anyway, but I digress . . .
Just repeat the activity a couple of times, taking up the cards, mixing them up, and repassing them out.
