(Using Color Tiles)

To find 8 – 5, place 8 tiles of one color and then remove 5 of the tiles. There are 3 tiles remaining, so 8 – 5 equals 3. The subtraction can also be modeled by placing 8 tiles of one color, and covering 5 of those tiles with another color. There are 3 tiles that are not covered, so 8 – 5 equals 3.
