The questions that trip children up
Problem sums are the multi-step word questions in Maths. They carry many marks in school exams and in PSLE Paper 2, so ALEC teaches how to answer them, not just the sums.
How to attack a problem sum
- Read it twice and say what the question asks.
- Underline the numbers, the key words and the question.
- Draw a bar model or table to see what is known.
- Work step by step and write units and working for method marks.
- Check that the answer makes sense.
