What students learn in AC9MFM01
This unit helps students build a clear, usable understanding of And compare attributes of objects and events, including length, capacity.... 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 and compare attributes of objects and events, including length, capacity, mass and duration, using direct comparisons and communicating reasoning.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- using language to describe the measurement attributes of length, mass, capacity and duration, and connecting the words with the appropriate attribute; for example, using words like “tall”, “short”, “wide”, “long”, “high” to describe the attribute of length directly comparing pairs of objects to say which is longer/shorter, and explaining or demonstrating how they know; for example, standing back-to-back to determine who is taller; choosing to line up the bases of a spoon and fork to decide which is longer and explaining why
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
Curriculum coverage and elaborations
The content description and elaborations below show the curriculum ideas taught in this unit. Items marked as teaching context support lesson planning but may not appear in the initial eight-question activity.
- Content description: identify and compare attributes of objects and events, including length, capacity, mass and duration, using direct comparisons and communicating reasoning
- E1: using language to describe the measurement attributes of length, mass, capacity and duration, and connecting the words with the appropriate attribute; for example, using words like “tall”, “short”, “wide”, “long”, “high” to describe the attribute of length
- E2: directly comparing pairs of objects to say which is longer/shorter, and explaining or demonstrating how they know; for example, standing back-to-back to determine who is taller; choosing to line up the bases of a spoon and fork to decide which is longer and explaining why
- E3: starting 2 events at the same time to decide which takes longer; for example, putting on a pair of sandals with buckles or Velcro, describing the duration using familiar terms and reasoning, “I took a longer time because I’m still learning to do up my buckles”
- E4: directly comparing pairs of everyday objects from the kitchen pantry to say which is heavier/lighter; for example, hefting a tin of baked beans and a packet of marshmallows; comparing the same pair of objects to say which is longer/shorter and discussing comparisons

- Rushing to a rule before checking the concrete model, drawing or number sentence.
- Using the correct answer once but not being able to explain why it works.
- Mixing up similar vocabulary such as more/less, before/after, longer/shorter or equal groups/sharing.
