What students learn in AC9MFN05
This unit helps students build a clear, usable understanding of Represent practical situations involving addition, subtraction and quantification with physical.... 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: represent practical situations involving addition, subtraction and quantification with physical and virtual materials and use counting or subitising strategies.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- using role-play and materials to represent mathematical relationships in stories; for example, “Eight kangaroos were drinking at the river and 3 hopped away”; drawing a picture and using materials to represent the situation, discussing, and recording the result of the action with a numeral role playing or actively engaging in situations that involve quantifying or comparing collections of items or simple money transactions; for example, “Do we have enough scissors for our group so that each person has their own pair?”; role-playing using \$1 coins to pay for items in a shop where items are priced in whole dollars
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
