Problem Sums?No Problem!
Master 14 Maths Heuristics, Step by Step
by Fara Azlin Buang
Problem sums, solved one heuristic at a time
Many students know their Maths but freeze when they meet a problem sum. This book gives them a plan. Each of the 14 heuristics is explained simply, broken into clear steps, practised with guided questions and then checked with self-practice questions.
Ideal for upper primary students preparing for the PSLE, parents supporting revision at home, and teachers and tutors looking for a structured approach to problem sums.
Inside this book
- Clear, step-by-step methods for 14 heuristics
- Fill-in-the-blank summaries that build real understanding
- 182 guided and self-practice questions with space for working
- A QR code in every chapter linking to a short video explainer
- An answer key for every self-practice question
