Pull the multiplier lever to build powers, lay rows to build squares, and arrange cells into perfect squares to find roots.
Three build-it mechanics make exponents concrete: pulling a ×2, ×3 or ×10 lever multiplies the energy cells while the exponent counts the pulls; squares are built row by row so n² emerges from an actual square shape; and square roots are proven by arranging loose cells into a perfect square whose side is the root. Best for Grades 5–6, or any child who has started exploring multiplication patterns and is ready to go further.
A free, no-signup, no-ads math game for Grades 5–6 — practising exponents, powers, squares. Play in your browser on the KidsDoMath games hub or explore more Arithmetic games.
