What students learn in AC9M2M05
This unit helps students build a clear, usable understanding of Identify, describe and demonstrate quarter, half, three-quarter and full measures.... 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, describe and demonstrate quarter, half, three-quarter and full measures of turn in everyday situations.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- identifying things that turn in the school environment; for example, the handle on a tap or a door, the dial or switch on a piece of equipment; identifying a half turn and a full turn, drawing a diagram and labelling it with arrows to show the direction and amount of turn giving and following instructions to move during an activity; for example, demonstrating and describing half, quarter and full turns in a choreographed dance
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
