Categorised accoring to the heuristics taught in each chapter, this series states clearly the conditions in which pupils can use each heuristic to solve problems. Pupils hone their thinking skills as they go through the solution to each example using the 4-step problem-solving approach. With alternative heristics provided whenever appropriate, pupils are able to gain exposure in selecting the right heuristic to solve any word problem.Categorised accoring to the heuristics taught in each chapter, this series states clearly the conditions in which pupils can use each heuristic to solve problems.
