Learning objective: Calculate supplied simple and experimental probabilities, use probability scales, judge fairness and find complements.

Curriculum anchor: England KS3 mathematics: record, describe and analyse frequency of outcomes of probability experiments and understand that probabilities of all possible outcomes sum to 1.

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 list equally likely outcomes, state the denominator and check that a probability lies between 0 and 1. Take a break when you need one.
