รายละเอียด(อย่างย่อ) "This is a resource book for teachers, parents and Primary 6 students who are interested in learning how to manage and solve higher-order thinking word problems. These problems usually require students to compare quantities, work with differences, transfer units from one item to another, match units, regroup units and/or work with common multiples in order to successfully solve them. In this respect, problem-solving strategies such as model-drawing, diagramming, tabling and listing are important tools to help organise the thinking process. This book will be an indispensable guide in learning the problem-solving strategies and techniques."--back cover
