About Sample Spaces Lab

Count combined outcomes and use stated set, table and tree information, including descriptions of Venn-diagram regions. Correct answers can trigger celebrations. Feedback and retry options depend on the game.

Curriculum purpose

Learning objective: Count possible combined outcomes, calculate set totals, and use the stated frequencies or branches in tables and trees.

Curriculum anchor: England KS3 mathematics: enumerate sets and combinations of sets systematically using tables, grids and Venn diagrams and generate theoretical sample spaces for combined events.

This game is designed as short independent practice after an idea has been introduced. It does not replace direct teaching, mathematical or scientific discussion, or an adult checking whether the learner can explain the idea away from the screen.

For parents and carers

Ask the learner to identify disjoint regions or stages, then check totals before calculating a probability. Take a break when you need one.
