This is a math center, that can be used for 4 separate file folder games. It includes 4 SETS at different levels- great for differentiating- simple teacher directions and student directions. Artwork- I did myself. Each frog has two numbers one of each foot. The student writes the correct symbol on the frog's fat belly. This was created for 2nd and 3rd grade students. *** BEFORE YOU DOWNLOAD*** I have a special bundle with 3 centers including this one for $5.
