Use this chart with 18 tens frames to count your days in school next year. Enlarge this at your local Office Supply Store (It cost me less than $4). I had mine made so that little sticker dots would fit in each square. I used two different colors to emphasize combinations that made 10. This file has a chart for Kindergarten through 3rd grade as well as a blank one. Next year, I am going to use the blank one to give me a "white board" space to record combinations of ten, tens and ones, or whatever suits the moment! Enjoy!
