分数应用题
Description
Solve word problems involving addition and subtraction of fractions with unlike denominators, using visual models and benchmark fractions to estimate and assess reasonableness
Mastery Evidence
- Solve: 'Tara ate 2/5 of a pizza and Sam ate 1/3. How much did they eat together?'
- Recognise that 2/5 + 1/2 ≠ 3/7 because 3/7 < 1/2 but the sum should exceed 1/2
- Estimate a fraction sum using benchmarks (0, 1/2, 1) before computing exactly
Assessment Prompt
If your child walks 1 and 1/2 miles to school and 3/4 of a mile to a friend's house, can they work out the total distance — and check whether their answer makes sense?
