Here is one of the math games I use to teach counting, one to one correspondence, addition, and subtraction. Students use their switch to spin. I color code the ends so that I can remember which switch to plug in for each child. I found that it is easier for each student to have a switch rather than pass one switch around. I use two 10 frames. Each space has a Velcro dot and each cube has Velcro. The spinner can be programmed with numbers to match IEP goals. I have found the game useful for teaching students to count on for addition. The first person to 20 wins.
