These cards are preformatted so you can easily print them off on 4x6 inch index cards, clip them together with a ring and use them! That way, you can make sets for every table in your classroom if you want to give students choice, or easily tell them to find #5 and follow the instructions. They all can be done in less than 5 minutes as a warm-up or closure activity.
The best part? None of these activities require any advance preparation for the teacher! After all, we are all a little tired!
