Dominoes give every number a shape a child can learn to spot. This Pre-K counting domino dots to 20 worksheet holds nine boxes of dominoes and dice. In each box, the child counts every dot and colors the total among three number choices. The first box is a worked example: ten dots, with 10 shaded in yellow. Some boxes stop at a handful of dots, while others reach 18, 19 or 20. One box even shows a blank die, so the answer there is zero.
