Build a probability spinner: set how many sectors win, then spin. Match a target chance as a fraction, shape likelihoods (certain/even/unlikely), and watch experiments converge on the theory in a live bar chart.
Children design a spinner by choosing how many sectors lead to a win, express the resulting chance as a fraction, and classify outcomes as certain, even, or unlikely. Repeated spins feed a live bar chart that shows how experimental data gradually approaches the theoretical probability. Best for Grades 4–6, or anyone curious about why a fair coin lands heads roughly half the time.
A free, no-signup, no-ads math game for Grades 4–6 — practising probability, data, statistics. Play in your browser on the KidsDoMath games hub or explore more Data & Probability games.
