Use the − / + buttons to build the same number of blocks in every tower (or drag up). Build the towers as tall as they can go equally; leftovers stay in the pool. If you take more blocks than there are, the towers turn red. Then press Check
3D math game · Best for grades 3-5
Division Towers (Long Division) turns the abstract steps of long division into a building challenge. A pool of blocks must be stacked equally into several towers. Students raise every tower to the same height, leaving any indivisible remainder blocks in the pool — making the quotient and remainder visible before the algorithm ever appears on paper.
Division Towers builds the quotitive division model (how many equal groups fit?) and gives long-division's sub-steps a concrete meaning: each floor of the tower corresponds to one cycle of divide-multiply-subtract in the formal algorithm. Students who build the towers first make far fewer errors when they meet written long division.
Pool: 29 blocks, 4 towers. Each tower grows to 7 (4 × 7 = 28), leaving 1 block in the pool. The towers show 7 per group; the pool shows remainder 1. 29 ÷ 4 = 7 remainder 1.
Students try to make towers of different heights, giving more to some towers than others. The game turns mismatched towers red, reinforcing that all groups must be equal — the definition of division.
Use it for individual practice, paired work, or a short class demonstration before worksheets.
Start with the game above, then continue with written practice to reinforce the skill.
