The Cambridge Lower Secondary Mathematics Learner's Book 8, authored by Lynn Byrd, Greg Byrd, and Chris Pearce, is designed to develop mathematical thinking skills in young learners. Aligned with the Cambridge International Lower Secondary Curriculum Framework, this book offers a variety of engaging activities, including learning about integers, expressions, formulae, equations, place value, rounding, decimals, angles, constructions, data collection, fractions, shapes, symmetry, sequences, functions, percentages, graphs, ratio, proportion, probability, position, transformation, and interpreting results. 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 skills they are developing, and 'Summary checklist' and 'Check your progress' exercises at the end of each unit help learners reflect on what they have learned. The book also includes answers for all activities in the accompanying teacher's resource. The 1-year digital access code offers interactive resources to support and enrich the learning experience.
