Elaboration on this Achievement Objective

This means students will recognise that probability is about the chance of outcomes occurring. Through activities that involve them personally, students at Level Two are expected to consider the possible outcomes of events in predicting what might occur. Through carrying out experiments, for example playing a game of chance, and making simple models of all the outcomes, for example lists or tables, students should recognise when outcomes appear to be equally likely, for example getting an even number when tossing a dice. Students should also recognise that where an event has more than one possible outcome they cannot predict the outcome with certainty, for example "it probably won’t be a six but it might be" when rolling a dice. Students should relate probability to events in their daily life, for example "it is very likely to rain today".

Cube and spinner challenges

Level Two
Statistics
Units of Work
In this unit we play several games based on coloured cubes and spinners. The purpose is to investigate chance and think about the concept of a fair game.
  • Recognise that not all things occur with the same likelihood.
  • Observe that some things are fairer than others.
  • Explore adjusting the rules of games to make them fairer.

Statements about probability

Level Two
Statistics
Units of Work
In this unit students make spinners to show the probability of events, make statements about probabilities shown on spinners, and evaluate statements made by other classmates.
  • Make statements about probabilities shown on a spinner.
  • Evaluate statements made about probabilities shown on a spinner.
  • Provide reasons to support their evaluation of the statement.

Level Two
Statistics
Units of Work
In this unit we play probability games and learn about sample space and a sense of fairness.
  • Use dice and related equipment to assign roles and discuss the fairness of games.
  • Play probability games and identify all possible outcomes.
  • Compare and order the likelihood of simple events.
