Tap every marble into the tray and watch the probability fraction build itself — then spin 20 times to test it!
Counting outcomes is the central skill — children work out how many combinations two independent choices can produce, determine the size of a sample space, or identify what total a probability is measured against. Systematic counting and multiplication are the core tools for reaching each answer. Designed for Grades 4–6, or any child beginning a first unit on probability.
A free, no-signup, no-ads math game for Grades 4–6 — practising probability, counting, multiplication. Play in your browser on the KidsDoMath games hub or explore more Data & Probability games.
