recognise that probabilities lie on numerical scales of 0 – 1 or 0% – 100% and use estimation to assign probabilities that events occur in a given context, using common fractions, percentages and decimals

How Bloomi helps with this

This is a readiness-year topic that builds towards the next NAPLAN year. Bloomi practises it as curriculum mastery, never test drilling.

What this looks like in the classroom

• recognising that the probability of an event occurring can be represented numerically as either a number ranging from zero to one or a percentage from \(0\)% to \(100\)% where zero or \(0\)% means it won’t happen and one or \(100\)% means it is certain to happen
• using a scale of zero to one or \(0\)% to \(100\)% to estimate chances of events
• listing the different possible outcomes for rolling a dice and using a scale to locate the relative probability by considering the chance of more or less than for each possible event; for example, the probability of getting a number greater than \(4\)
