This "Teacher"s Guide" has been specifically written for the Higher tier of the two-tier linear Edexcel GCSE Mathematics specification. It is designed to accompany the "Higher: Students" Book" in the same series, which is written for students who have achieved level 6 or a strong level 5 at Key Stage 3 and are looking to progress to a grade В or С at GCSE. The series authors are experienced teachers and examiners who have an excellent understanding of the Edexcel two-tier specification and so are well qualified to help you successfully implement the objectives in your classroom. The book is made up of units which are based on the Edexcel specification, and provide full lesson plans for each of the lessons in the corresponding "Students" Book".
