I created this set of "Ten-Frame" mats to help my kinders begin to understand how to organize in groups of ten. They could easily be used with 1st graders as well. You could also use in a Math Center.
This is a set of 47 Halloween themed "Ten-Frame" mats to help students organize materials in a mathematically meaningful way. Ten-frame mats also help young students organize objects by tens, reinforcing that important place value concept of our base-ten number system.
