Sample Spaces Lab

Free Year 7 Maths practice — enumerate combined outcomes and reason with Venn diagrams, tables and trees. No account needed.

About Sample Spaces Lab

Enumerate combined outcomes and interpret supplied Venn diagrams, two-way tables and vertical trees. The default practice mode is untimed, so the learner can think before choosing. Correct answers build a gentle celebration; mistakes receive corrective feedback and return later rather than causing a penalty spiral.

Curriculum purpose

Learning objective: Enumerate supplied combined outcomes and interpret bounded Venn diagrams, two-way tables and vertical 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. Stop while attention is still good. A short accurate return tomorrow is more useful than extending a tired session today.

Frequently asked questions

Does it need an account? No. The game runs in the browser and asks for no name, email address, school or location.

Is it timed? Practice is untimed. Where a sprint exists it is optional. Times Tables Sprint also includes MTC-style independent practice, not an expected-standard judgement.

Can it be used on a phone? Yes. Buttons support touch and keyboard use; sorting always has a tap alternative to dragging.
