Students will be working with numbers to 20. This center comes in color and black and white. There are four different sets and two record sheets. Two sets cover numbers 0-10 and two cover numbers 10-20. I've also included a cover sheet for each set for organizing. You can put these in a photo box or on a book ring to store when you aren't using them. These are small (quarter sheet) and simple to prep. Just print, laminate, and make a few straight cuts. Enjoy!
