Written in a clear and accessible way, this book guides the reader through the fundamental ideas at the heart of teaching and learning maths, with special focus on observation and assessment of primary and early years children. This new edition includes Resource Inspiration boxes providing inviting examples of classroom activities. High-quality videos with corresponding discussion have been expertly selected from Teachers TV, offering tips, lesson ideas and classroom resources. 'This is a really useful book for beginning teachers. It grounds subject knowledge in mathematics pedagogy and focuses on how teachers can support pupils' attainment in mathematics through understanding maths rather than memorising tricks and procedures.'Sal Jarvis, Associate Dean: International, Enterprise and Communities, School of Education, University of Hertfordshire, UK
