What students learn in AC9M1M03
This unit helps students build a clear, usable understanding of Time: years, months, weeks, days and hours. The goal is not to memorise one answer pattern. Students should be able to explain the idea, recognise it in a new example and apply it in a short practice or worksheet task.
- Start with the main idea: describe the duration and sequence of events using years, months, weeks, days and hours.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- naming, listing and using familiar units of time, such as hours, days, weeks, years comparing the number of days in the months of the year and explaining how the months cycle from one year to the next
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
