This is a great game that students can use to review. I have used it as one station that students can participate in during a class review day. Students flip all the cards upside down and flip two over at a time. If the word and definition match, they keep the set. Students must be paying attention so they know where the words and definitions are when they need them.
I cut these out and put them on colored card-stock so I can still use a black and white printer but can make them look a little jazzier with colored paper. I also recommend laminating them so they last a little longer.
