I made these tens frames to use on my whiteboard. I attended a great Math in Focus PD this summer and the instructor used these during her example lessons very often. I created my own set to use. They are big and easy to see.
I updated this set to have 3 different colors for you. There's a set 1-10 with red/yellow counters, plain black, and blue.
These are great to use for "quick images" to help students with subitizing and number sense!
