Skills focussed series, working towards endorsement, for examination from 2023; inspired by teachers, for teachers. The maths skills workbook with digital access helps learners to develop their maths skills in the context of the Cambridge IGCSE™ Chemistry syllabus, based on research carried out by the Nuffield Foundation and the Association for Science Education. Practice exercises, which increase in complexity, provide opportunities for learners to practise each maths skill. Worked examples help learners develop their thinking processes and include further help with 'Key questions to ask yourself'. The 'Look out' feature makes students aware of common misconceptions. Practice and exam-style questions help students improve their fluency and confidence in answering questions. The answers can be found online at www.cambridge.org/go
