B5 Mathematics · Term 3 Week 11: Chance (Probability)

Lesson notes

Learning Objectives

Indicator: B5.4.2.1.2 - Design and conduct an experiment in which the likelihood of a single outcome occurring is impossible, possible (likely or unlikely), certain.

By the end of the lesson, learners can:

Design a simple probability experiment using everyday materials such as bottle tops, coloured counters, or cards.
Conduct the experiment they designed, recording each outcome accurately as it occurs.
Classify the likelihood of each outcome from their experiment as impossible, possible (likely or unlikely), or certain, using the language of chance.
Explain in their own words, with justification, why a particular outcome is impossible, possible, or certain based on the contents of their experiment.
Work cooperatively in small groups to design, run, and report on a probability experiment, sharing responsibilities and results clearly.

Exemplars (from the NaCCA curriculum)

E.g. In a bag containing 10 red, 4 green and 1 pink bottle tops, let a learner pick one bottle top from the bag. 1. Picking a black bottle top is impossible 2. Picking a red bottle top is possible (likely) 3. Picking a pink bottle top is possible (unlikely) 4. Picking a red or green or pink bottle top is certain. Explain each of the four outcomes
