What students learn in AC9M3N02
This unit helps students build a clear, usable understanding of And represent unit fractions including \frac12, \frac13, \frac14, \frac15 and.... 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 and represent unit fractions including \frac12, \frac13, \frac14, \frac15 and \frac1{10} and their multiples in different ways; combine fractions with the same denominator to complete the whole.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- recognising that unit fractions represent equal parts of a whole; for example, one-third is one of 3 equal parts of a whole representing unit fractions and their multiples in different ways; for example, using a Think Board to represent three-quarters using a diagram, concrete materials, a situation and fraction notation
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
Curriculum coverage and elaborations
The content description and elaborations below show the curriculum ideas taught in this unit. Items marked as teaching context support lesson planning but may not appear in the initial eight-question activity.
- Content description: recognise and represent unit fractions including \frac12, \frac13, \frac14, \frac15 and \frac1{10} and their multiples in different ways; combine fractions with the same denominator to complete the whole
- E1: recognising that unit fractions represent equal parts of a whole; for example, one-third is one of 3 equal parts of a whole
- E2: representing unit fractions and their multiples in different ways; for example, using a Think Board to represent three-quarters using a diagram, concrete materials, a situation and fraction notation
- E3: cutting objects such as oranges, sandwiches or playdough into halves, quarters or fifths and reassembling them to demonstrate; for example, two-halves make a whole, four-quarters make a whole, counting the fractions as they go
- E4: sharing collections of objects, such as pop sticks or counters, between 3, 4 and 5 people and connecting division with fractions; for example, sharing between 3 people gives \frac13 of the collection to each and sharing between 5 people gives \frac15 of the collection to each

- 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.
