📝 Helpful Tips

These practical activities are designed to support AC9M3N07:

Look for patterns in numbers. Encourage students to notice repeated endings, skip-counting patterns, and relationships between numbers.
Use mental maths strategies. Doubling, halving, grouping, and partitioning numbers help students calculate more efficiently.
Connect maths to real life. Practise counting coins, sharing objects, and solving everyday problems involving money and quantities.
Explain the strategy used. Students should talk about how they solved the problem, not just give the answer.
Check answers using estimation. Encourage students to decide whether answers make sense before finalising them.
Practise flexible thinking. There are often multiple ways to solve a modelling problem — students should explore and compare strategies.
