What students learn in AC9M2M03
This unit helps students build a clear, usable understanding of The date and determine the number of days between events.... 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: identify the date and determine the number of days between events using calendars.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- using calendars to locate specific dates and identify what day it is, to determine the date 2 weeks prior to or after a given date creating a class calendar to enter specific dates relevant to the class; for example, students’ birthdays, school assemblies, sports carnivals or class excursions
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
