"Slam Dunk to 20: A Basketball-Themed Counting Game" is a learning center that can be completed individually or played with multiple players. It includes a game mat that features basketballs labeled with the numbers 0 to 20. Students spin the spinner and move their mini eraser or other game piece ahead one, two, or three spaces depending on where the spinner lands. There's also a space where students lose a turn. As they count up, they can see the addition problem that is created. For example, if they are on the "3" space and get a "2," they can see that they start at 3, add 2, and end up at the number 5. This supports counting up skills and builds a foundation for more complex addition later.

The learning center includes directions that help teachers assemble everything students will need, along with separate directions that help students learn how to play the game. There is also a handy section that gives teachers ideas on how to create the spinner with different materials, like a fidget spinner, a paper clip, or a plastic piece attached to a brass fastener.
