Print each set of multiples on a different color of paper to make them easier to store. Counting by 2s, 3s, 4s, 5s, 6s, 7s, 8s, and 9s quickly makes multiplication easier. This is a wonderful center idea. You'll want to make an anchor chart of the multiples to add support for your students while they're learning their multiples. This was created on 1/15/18.
