Shaping Maths Activity Book 1a (3rd Ed) 45a5g

Preface Shaping Maths (3rd Edition) is an instructional package written according to the 2013 Ministry of Education, Singapore primary mathematics syllabus. The package is designed to meet the learning needs of pupils from Primary 1 to 6. The Primary 1 package consists of two Coursebooks, two Activity Books and two Teacher’s Planning Guides. Continuing research in education has resulted in the introduction of new features in the third edition. Through these features, educators are further equipped with various strategies in addressing teaching and learning needs. These features include handson activities, group/pair work and open-ended questions to encourage exploration and in-depth thinking among pupils. This will equip pupils well for the challenges of the 21st century.
