Still the biggest concern for many on initial teacher training courses is the acquisition of subject knowledge and the ability to translate that into effective teaching. This book addresses this - building on the core subject knowledge covered in the Achieving QTS series and relating it to classroom practice. It supports trainees in extending and deepening their knowledge of Maths and demonstrating how to apply it to planning and implementing lessons. Practical and up-to-date teaching examples are used to clearly contextualize subject knowledge. A clear focus on classroom practice helps trainees to build confidence and develop their own teaching strategies.
