Spinner Workshop: Probability Game for Grades 7‑8
Build toy and board-game spinners that hit an exact chance, then test them.
Customers at a toy and board-game workshop order spinners with a target probability. Mark the sectors to match the chance, run simulated test spins to compare what happens with what should happen, read the chance off a finished spinner, and predict how many times an outcome will turn up in many spins.

What kids practise
Spinner Workshop gives students repeated, low-pressure practice with probability, probability models, simulation, relative frequency, and compound outcomes. It is written for grades 7-8, with levels that let younger and older players start at the right difficulty. Every question is generated fresh, so a replay is never the same, and a wrong answer shows the correct one so the round teaches as well as tests.
How it plays
Controls: Tap a sector or use the Stars/Moons buttons to mark the spinner; Left/Right arrows move between sectors and Space marks one; tap or press 1-4 for multiple-choice orders; P pauses, M mutes.
It works with a keyboard, a trackpad or a touch screen, so it runs on school Chromebooks, tablets and phones.
