This is a proven successful and traditional model from these authors. Each chapter presents the necessary text, fully worked examples and plenty of carefully graded questions. Each book starts with a summary of the main results from the previous books for continuity. Summaries and revision exercises are phased through the books to provide extra consolidation work. Practical work, investigations or puzzles feature in every chapter – Ma1 activities are explicit and relevant to the mathematics being learned. Challenge questions are included to stretch the most able pupils.
