describe possible everyday events and the possible outcomes of chance experiments and order outcomes or events based on their likelihood of occurring; identify independent or dependent events

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

• using lists of events familiar to students and ordering them from “least likely” to “most likely” to occur; considering and discussing why the order of some events might be different for different students
• predicting the outcome of a coin toss after \(5\) heads have been flipped in a row, discussing the assertion that because so many heads came up, it is more likely that a tail rather than a head will come up next; discussing with reasons why the assumption is correct or incorrect
• predicting how likely, from least likely to most likely, of selecting a red ball from a bag containing \(10\) red balls and \(5\) white balls, a bag containing \(20\) of each, or one that has \(25\) red balls and \(20\) white balls, justifying their decision
