Example: 18 gum balls are packed into a coin-operated machine on one of the worksheets. Inside each gumball is a single subtraction problem. Once students have completed the math drills, they are directed to color the gum balls. A sphere with the answer 4 or 5, for example, should be colored blue.

Not only do students get to practice their math, they improve their skills at following directions. Visual subjects range from “ice cubes” to “paint cans”. Math difficulty peaks with subtracting single-digits from double-digits. There are 22 worksheets and an Answer Key included. Grade Level 2
