What students learn in AC9M4M01
This unit helps students build a clear, usable understanding of Interpret unmarked and partial units when measuring and comparing attributes.... 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: interpret unmarked and partial units when measuring and comparing attributes of length, mass, capacity, duration and temperature, using scaled and digital instruments and appropriate units.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- reading the mass of objects measured with digital and analog kitchen scales and explaining what unit of mass the lines on the analog scales refer to deciding on which attribute, unit and measuring instrument to use to compare the length and mass of various things, such as the distance travelled by an object in a science investigation; explaining the use of units such as grams or millimetres to give accurate measures when needed
- 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: interpret unmarked and partial units when measuring and comparing attributes of length, mass, capacity, duration and temperature, using scaled and digital instruments and appropriate units
- E1: reading the mass of objects measured with digital and analog kitchen scales and explaining what unit of mass the lines on the analog scales refer to
- E2: deciding on which attribute, unit and measuring instrument to use to compare the length and mass of various things, such as the distance travelled by an object in a science investigation; explaining the use of units such as grams or millimetres to give accurate measures when needed
- E3: using scaled instruments such as tape measures, measuring jugs, kitchen scales and thermometers, recording measures using whole units; for example, 560 millimetres, or whole and part units; for example, 5.25 metres, 1.75 litres, 2.5 kilograms, 28.5° Celsius
- E4: reading and interpreting the scale of an analog clock without marked minutes to estimate the time to the nearest minute and to determine the duration of time between events
- E5: using the timer or alarm function of a clock to alert when a specified duration has elapsed from a given starting time; for example, the different activities of an exercise routine
- E6: making a scaled measuring instrument such as a tape measure, ruler, sand timer, sun dial or measuring cup using scaled instruments and direct comparisons
- E7: exploring the different types of scaled instruments used by First Nations Ranger Groups and other groups to make decisions about caring for Country/Place, and modelling these in local contexts (teaching context)
How to use this unit
Read the topic guide, use the teacher slide for instruction, then complete the Worksheet, Practice and Test. These three activities use the same eight-question unit bank.

- 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.
