What students learn in AC9M2A03
This unit helps students build a clear, usable understanding of Recall and demonstrate proficiency with multiplication facts for twos; extend.... 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: recall and demonstrate proficiency with multiplication facts for twos; extend and apply facts to develop the related division facts using doubling and halving.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- recognising and relating terms such as double, twice and multiply by 2, halve and divide by 2 using physical and virtual materials; for example, colouring numbers on a hundreds chart to represent doubles and use to recognise halves; recognising the doubling pattern and applying to find related facts such as for 8 twos think 2 eights doubling and halving collections to practise and develop fluency with multiplication and division facts for twos leading to recall of these facts
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.

- Content description: recall and demonstrate proficiency with multiplication facts for twos; extend and apply facts to develop the related division facts using doubling and halving
- E1: recognising and relating terms such as double, twice and multiply by 2, halve and divide by 2 using physical and virtual materials; for example, colouring numbers on a hundreds chart to represent doubles and use to recognise halves; recognising the doubling pattern and applying to find related facts such as for 8 twos think 2 eights
- E2: doubling and halving collections to practise and develop fluency with multiplication and division facts for twos leading to recall of these facts
- E3: establishing an understanding of doubles and near doubles using physical or virtual manipulatives; for example, using manipulatives to establish that doubling 5 gives you 10 then extending this doubling fact to respond to the question, “How can you use this fact to double 6 or double 4?”
- E4: develop fluency with doubling and halving numbers within 20 using physical or virtual materials and playing doubling and halving games; for example, using a physical or virtual dice and choosing whether to double or halve to reach a target number
