Year 5 Probability Unit

Build confident probability reasoning across a complete week of Year 5 mathematics. This unit begins with chance language and complete sample spaces, then develops equal and unequal likelihood, probability as a fraction from 0 to 1, card and spinner contexts, two-dice outcomes, repeated experiments, expected and observed frequency, independence and fair-game reasoning.

The 16-slide editable presentation supports explicit teaching and discussion. Colour resources provide a display, sorting activity and two games, while black-and-white practice pages give students room to list outcomes, calculate probabilities and justify conclusions. The two-page Experimental Probability Lab supports prediction, 40-trial data collection, group comparison and method evaluation. The two-page Carnival Chance Investigation and five-level rubric provide a focused assessment of theoretical and experimental probability.

Ten matching answer pages reproduce the relevant worksheet and assessment layouts with a red ANSWERS label and red answers placed in the response spaces. A 22-slide editable quiz provides 10 question-and-answer pairs for whole-class review.

Learning Focus

• List complete possible outcomes for chance experiments
• Distinguish equally likely from unequally likely outcomes
• Express theoretical probability as fractions between 0 and 1
• Compare likelihoods using probability language and number-line positions
• Analyse cards, spinners and the 36 ordered outcomes for two dice
• Conduct and record repeated chance experiments
• Use observed frequency to estimate and compare likelihood
• Explain variation, independence and fairness using evidence

Classroom Use

Use the presentation to introduce and model each concept, then select the display, sorting cards or games for guided and collaborative practice. The worksheets move from review to deeper comparison and reasoning. Use the Experimental Probability Lab for a practical lesson and class-data discussion, then complete the quiz or Carnival Chance Investigation as formative or summative assessment.
