The Cambridge Primary Mathematics Learner's Book 5, authored by Mary Wood and Emma Low, is designed to develop mathematical thinking skills in young learners. Aligned with the Cambridge International Primary and Lower Secondary Curriculum Frameworks, this book offers a variety of engaging activities, including learning about rounding decimal numbers and calculating time intervals on a train timetable. Each unit begins with a 'Getting started' feature to activate prior knowledge, followed by clearly identified activities throughout each unit. 'Think like a mathematician' provides learners with investigation activities linked to the skill, and 'Look what I can do!' statements in each section help learners reflect on what they have learned. The book also includes a 'Check your progress' exercise at the end of each unit. Answers for all activities can be found in the accompanying teacher's resource. The 1-year digital access code offers interactive resources to support and enrich the learning experience.
