The maths skills workbook helps learners to develop their maths skills in the context of the Cambridge IGCSE™ Biology syllabus. These skills are crosslinked to the coursebook to help students understand how to use them. Practice exercises provide opportunities for learners to practise each maths skill. To support students in acquiring these skills, the exercises gradually increase in complexity. Practice questions provide opportunities for students to practise their skills in an active learning format such as discussion opportunities and pair work. Exam-style questions give students the chance to apply the skills they have learnt in an exam-style context. In the last chapter, students will need to select which maths skills they ought to apply in different contexts, without the structure and guidance provided in each of the chapters, helping them become confident, independent learners. The answers can be found online at www.cambridge.org/go
- Written by experts in both biology and mathematics based on research carried out by the Nuffield Foundation and the Association for Science Education (ASE)
- Maths skills are crosslinked to other resources in the series to help students understand how to use them
- Practice exercises gradually increase in complexity to support students in developing maths skills
- Worked examples illustrate the concept, provide a skills-based step-by-step approach to answering a question, helping learners to develop their thinking processes
- The ‘Look out’ feature makes students aware of common misconceptions that might be holding them back
- Exam-style students require students to select which maths skills they ought to apply in different contexts, without the structure and guidance provided in each of the chapters, helping them become confident, independent learners
