Subtracting Integers with Two-Color Counters

Subtraction can be thought of as removing or taking away. To subtract 5 – (-3), start by modeling the first number with 5 positive counters. Next remove 3 negative counters. Since there are not enough negative counters, add 3 zero pairs and then remove 3 negative counters. There are 8 positive counters remaining, so 5 – (-3) = 8.
