Primary Mathematics Teacher Guides provide, in both flexibility and detail, a clear framework for the Primary Mathematics textbooks. Each lesson is accompanied by numerous activities which expand and reinforce the concepts for that lesson and which are designed to fit both teachers who wish to adapt lessons to their own classroom situation, and teachers who desire easy-to-follow, effective teaching strategies. Through the notes to the teacher and the detailed objectives for each learning task in the text and activity in the guide, these Teacher Guides help teachers to fully understand the purpose and concept behind each set of problems, both within the context of the unit and the context of the overall curriculum. The teacher's guide contains answers for the textbooks and workbooks. Grade 4A
