This Smartboard game is from the Everyday Mathmatic's series for first grade. It is a two player game that has the students practice adding and subtracting using a number line. They will roll the interactive die on the Smartboard and then will move their bunny to the carrots which is located on 20. Once they get their bunny to the carrots the students have to roll the die but subtract back to the bunny hole which is 0 on the number line. Very cute game!
