Everyone has seen Race to 20 game boards. I decided to make them for my class and my class needs differentiation. I have all levels-high and low. This game allows my remedial children to play very similar games to my high kids. It allows my middle kids to bump up when ready. One board has all the numbers, one has traceable numbers, one has no numbers but a number line for modeling and another with no numbers or number line. My high kids can play on their board with a low kid--each with his/her own level game board. Have fun learning and playing!
