What students learn in AC9M2N01
This unit helps students build a clear, usable understanding of Recognise, represent and order numbers to at least 1000 using.... 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 numbers to at least 1000 using physical and virtual materials, numerals and number lines.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- recognising missing numbers on different number lines; for example, a number line with 1800 on one end and 220 on the other, with every decade numbered recognising and locating the position of pieces within hundreds chart puzzles using knowledge of the order of natural numbers
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.

- E1: recognising missing numbers on different number lines; for example, a number line with 1800 on one end and 220 on the other, with every decade numbered
- E2: recognising and locating the position of pieces within hundreds chart puzzles using knowledge of the order of natural numbers
- E3: reading and writing numerals, and saying and ordering two-, three- and four-digit numbers using patterns in the number system, including numbers with zeros in different places, and numbers that look and sound similar such as 808, 880, 818 and 881
- E4: collecting large quantities of materials for recycling; for example, ring pulls, bottle tops and bread tags, and grouping them into ones, tens and hundreds; using the materials to show different representations of two- and three-digit numbers
