(From The Mailbox)
To prepare, obtain a large cardboard circle and a clean pizza box. Decide how many colors you’d like to include; then use a marker to divide the cardboard circle into that many sections. For each slice in your pizza, cut out one colored construction paper pizza slice and one white one. Cut off a crust shape from each colored slice, and then glue each crust to a white pizza slice. Program each white slice with the color of the crust. Then glue these slices to the cardboard circle. Next, program each (crustless) colored slice with the corresponding color word. Place the pizza and the pieces in the box and store it in your center. To use this center, a child matches each colored slice of pizza to the crust and the color word.
