What students learn in AC9M3M01
This unit helps students build a clear, usable understanding of Which metric units are used to measure everyday items; use.... 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 which metric units are used to measure everyday items; use measurements of familiar items and known units to make estimates.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- examining the packaging on supermarket items to determine the metric unit used to describe the mass or capacity of the contents identifying items that have a mass of one kilogram or 500 grams, or a capacity of one litre or 500 millilitres and using these benchmarks to estimate the mass or capacity of other things, explaining their reasoning
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.

- E1: examining the packaging on supermarket items to determine the metric unit used to describe the mass or capacity of the contents
- E2: identifying items that have a mass of one kilogram or 500 grams, or a capacity of one litre or 500 millilitres and using these benchmarks to estimate the mass or capacity of other things, explaining their reasoning
- E3: estimating the height of a tree by comparing it to the height of their friend and quoting the result as “the tree is about 3 times as tall”; estimating the capacity of a fish tank by using a litre milk carton as a benchmark
- E4: choosing and using metres to estimate the dimensions of the classroom
