Mathematics
Leigh worked through a fractions worksheet that required converting mixed numbers to improper fractions and adding and subtracting fractions with unlike denominators. By rewriting mixed numbers, Leigh reinforced understanding of the relationship between numerators and denominators and how to move between the two forms. While solving addition and subtraction problems, Leigh applied common‑denominator strategies, simplified the results, and checked the answers for reasonableness. This practice helped Leigh strengthen procedural fluency and conceptual grasp of fraction operations appropriate for a 12‑year‑old.
Tips
1. Have Leigh apply fraction skills to a real‑world cooking project by scaling a simple recipe up or down, which reinforces conversion and operation skills in a tasty context. 2. Introduce a fraction board game or online app where players must quickly convert mixed numbers and perform addition or subtraction to advance, turning practice into play. 3. Challenge Leigh to write and solve their own word‑problem scenarios involving mixed numbers, then exchange problems with a peer for peer‑teaching. 4. Use a large number line on the floor where Leigh physically places tiles representing each fraction from the worksheet, visualising magnitude and the effect of adding or subtracting.
