I'm trying something new this year doing "Math Stations." Here are a couple things I've made to use. The 120 chart I plan to use several ways. One is as a puzzle. I copied it on different colors of card stock then cut it into different sections. The students have to put it back together.
This Ways to Add is also copied on card stock and the facts cut out. Students have to sort the facts into the correct categories. Click on the image to download.
