Repeated Chance Experiments Year 5 Unit

Teach repeated chance experiments through a clear sequence of prediction, practical investigation, data recording, comparison and explanation. Students explore fair and unequal outcome structures using spinners, dice, coins, cards and marbles, then compare observed frequencies with expected likelihoods and consider why results vary between samples.

The unit combines a 19-slide editable lesson presentation with colourful reference materials, two games, five chance stations and five low-ink worksheet sequences. A two-part Chance Carnival investigation assesses students' ability to conduct, record and interpret experiments, while a five-level rubric supports consistent judgement. The editable 10-question quiz provides immediate answer slides and uses true/false, short-answer and four-option multiple-choice questions.

Learning focus

• Identify possible outcomes and describe event likelihood.
• Predict results before testing.
• Conduct fair and repeatable chance experiments.
• Record frequencies accurately and calculate relative frequency.
• Compare observed results with expected likelihoods.
• Explain sample variation and the stabilising effect of larger samples.
• Recognise equal, unequal, fair and biased outcome structures.
• Design and explain a fair chance experiment.

Classroom use

Use the presentation for explicit teaching and worked examples, then rotate groups through spinner, dice, coin, card and marble investigations. The games and station cards support collaborative practice. Worksheets provide independent consolidation, the quiz checks understanding, and the Chance Carnival task can be used for assessment.
