Measurement, chance and data

1.0 Standard

… Students recognise and respond to unpredictability and variability in events, such as getting or not getting a certain number on the roll of a die in a game or the outcome of a coin toss.

1.25

• Awareness that some events are equally likely to occur; for example, a head or a tail showing when a coin is tossed

1.5

• Knowledge of the outcomes of chance events such as rolling a die

1.75

• Ordering of familiar events in terms of their probability between impossible and certain

2.0 Standard

… Students predict the outcome of chance events, such as the rolling of a die, using qualitative terms such as certain, likely, unlikely and impossible.

2.5

• Identification of events which are equally likely

2.75

• Comparison of the likelihood of everyday events and linking of events with statements about how likely they are to occur

3.0 Standard

… Students compare the likelihood of everyday events (for example, the chances of rain and snow).

They describe the fairness of events in qualitative terms.

4.0 Standard

… Students calculate probabilities for chance outcomes (for example, using spinners) and use the symmetry properties of equally likely outcomes.
