This practical book will help you to explain key mathematical concepts to your students. Written as a series of example lessons, it focuses on teaching for mathematical understanding and helping students to develop skills they can transfer to other subjects. The book covers all aspects of the secondary mathematics curriculum for ages 11-18 and reveals how you can build on students' existing knowledge to help them make sense of new concepts and avoid common misconceptions. It is essential reading for all trainee and practising teachers that want to make mathematics relevant and engaging for their students.…mehr
