This is an easy activity to practice the months of the year. Write the months on a piece of paper, let the kids cut them out (this will buy you at least five minutes free time) and then let them rearrange them in order. You can also do this with days of the week, planets... anything that needs to be put in order. And since you didn't spend a lot of time making these by printing them, laminating them, cutting them out just perfectly, you don't even have to keep them. Just toss them when you are done reviewing.
