Long Division

This set consists of 4 colour-coded division boards and a wooden tray that holds seven racks of tubes with beads, 7 cups, and 36 skittles. Each tube holds 10 beads, for a total of 700.

This material forms the bridge to abstraction for the decimal system exercise of division. Using it, the child performs short and long division with dividends up to the millions and divisors from 1 to 4 digits.
