These flash cards are really great for review. You can even carry them around with you throughout the day and ask students questions whenever you have downtime (in the lunch line, etc.). I've been using this as a rotation during centers to review for our end of the year test!
Print these cards one-sided. The front of each card is on the left and the back is on the right. I made these so that each card can be folded and the answer will be on the back.
