What students learn in AC9M1N03
This unit helps students build a clear, usable understanding of Skip counting and equal groups. 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: quantify sets of objects, to at least 120, by partitioning collections into equal groups using number knowledge and skip counting.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- counting a large collection of items using groups of fives or tens and skip counting to work out how many there are; recording the amount and connecting the digits in the number to the grouped materials when using groups of 10 counting collections of objects such as pencils or images of birds in a tree, by grouping them in tens to enable efficient counting and connecting the digits in the number to the groups of tens and ones
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.

- 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.
