Starter Block Set The initial Starter Set is an 80-piece set of colorful, base 10, stacking blocks used to teach all aspects of arithmetic. These are also used with the Inserts to illustrate beginning algebra and decimals. There are four each of the 2s, 3s, 4s, 5s, 6s, 7s, 8s, 9s, and 100s; twenty 10s; and twenty-four units.
