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.

LEARNING FOCUS

• Possible events and outcomes of chance experiments.

• Impossible, unlikely, equally likely, likely and certain.

• Ordering outcomes and events by likelihood.

• Equal and unequal outcome sets.

• Predictions, repeated trials, frequency records and evidence-based conclusions.

• Independent and dependent events.

CLASSROOM USE

Use the presentation to introduce one concept at a time, then select the matching hands-on or printable task. The sorting cards, game and spinner page suit partner or small-group work. The worksheet sequence provides support, core practice and reasoning. Roll, Record and Reflect works as an investigation lesson, while Create a Chance Game provides extension. Finish with the editable quiz and School Fair Chance Investigation.
