What students learn in AC9M5M01
This unit helps students build a clear, usable understanding of Choose appropriate metric units when measuring the length, mass and.... 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: choose appropriate metric units when measuring the length, mass and capacity of objects; use smaller units or a combination of units to obtain a more accurate measure.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- ordering metric units from the largest unit to the smallest; for example, kilometre, metre, centimetre, millimetre recognising that some units of measurement are better suited to some tasks than others; for example, kilometres are more appropriate than metres to measure the distance between 2 towns
- 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: choose appropriate metric units when measuring the length, mass and capacity of objects; use smaller units or a combination of units to obtain a more accurate measure
- E1: ordering metric units from the largest unit to the smallest; for example, kilometre, metre, centimetre, millimetre
- E2: recognising that some units of measurement are better suited to some tasks than others; for example, kilometres are more appropriate than metres to measure the distance between 2 towns
- E3: deciding on the unit required to estimate the amount of paint or carpet for a room or a whole building; justifying the choice of unit in relation to the context and the degree of accuracy required
- E4: measuring and comparing distances, such as jumps or throws using a metre length of string; for example, then measuring the part metre with centimetres and/or millimetres; explaining which unit of measure is most accurate
- E5: researching how the base units are derived for the International System of Units (SI), commonly known as the metric system of units, recognising that the metric unit names for the attributes, length and mass are international standards for measurement

- 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.
