This practical book draws on Ronit Bird's teaching experience to create detailed strategies and teaching plans for students aged 9-16 who have difficulties with number. Activities and games are used to teach numeracy skills in these key areas: number components, bridging, multiplication, division and reasoning strategies. New to this edition: (1) An updated Part I, improving the clarity and flow of the teaching ideas, including a table mapping games against specific teaching points; (2) More activities and guidance for multiplication and division; (3) A new Part V, consolidating new and existing teaching games in one place; and (4) 4 new videos added to the online resources. This is an ideal resource for class teachers, SENCO (Special Educational Needs Co-ordinator) and maths subject leader, and is equally useful for teaching assistants and learning support assistants.
