I made a simple place value mat for my students use with blocks. I plan to use uni-fix cubes so I made it portrait since a *10* is pretty tall. I hope it makes your life a little easier.
*I do NOT have the amazing skills of most of the teachers on this site to create beautiful, professional looking items with adorable clip art. But, I do enjoy creating things that I need to help my students. The things I have listed are all things created out of necessity to help my own students. I hope they will help your students too.*
