Set the mystery shape's weight so a hanging mobile hangs level — the beam tilts live until both arms match.
A hanging mobile tilts until the child sets the mystery shape's weight so both arms weigh the same — across simple pairs, three-shape mixes, and nested arms. Balancing sums is early equation-solving you can watch. Best for Grades 3–6.
A free, no-signup, no-ads math game for Grades 3–6 — practising balance, equal-sums, reasoning, missing-value, equations. Play in your browser on the KidsDoMath games hub or explore more Patterns & Logic games.
