Year 4 Chance Unit

Build confident chance reasoning through a sequenced Year 4 Mathematics unit that connects familiar events with practical experiments. Students learn to describe possible outcomes, use likelihood language precisely, order events from impossible to certain, compare equally likely and unequal outcomes, and explain whether events are independent or dependent.

The 22-slide editable presentation supports explicit whole-class teaching. Colour resources include the Chance Language Poster, two-up Chance Detective reference card, Likelihood Line Sort, Probability Trail Game and Spinner Studio. Black-and-white print pages provide guided practice, repeated-trial investigation, reasoning space, an open-ended design challenge and a two-page assessment. The separate editable quiz includes 10 questions with matching answer slides. Nine answer pages and a five-level rubric support review and marking.
