What students learn in AC9M3N01
This unit helps students build a clear, usable understanding of Recognise, represent and order natural numbers using naming and writing.... 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: recognise, represent and order natural numbers using naming and writing conventions for numerals beyond 10 000.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- moving materials from one place to another on a place value model to show renaming of numbers; for example, 1574 can be shown as one thousand, 5 hundreds, 7 tens and 4 ones, or as 15 hundreds, 7 tens and 4 ones using the repeating pattern of place value names and spaces within sets of 3 digits to name and write larger numbers: ones, tens, hundreds, ones of thousands, tens of thousands, hundreds of thousands, ones of millions, tens of millions; writing, for example, four hundred and twenty-five thousand as 425 000
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
