Color Chips-Subtraction

This virtual manipulative is designed to help conceptualize the subtraction of integers. Positive integers are black chips and negative integers are red chips. Dragging a single black on top of a red chip together makes the pair disappear (visually emphasizing that the sum is 0). Users may practice problems generated by the computer, themselves or free play with the chips. There are separate tabs to access information for the user, the teacher and to seek help with instructions.
