Numicon builds a deep understanding of maths through a multi-sensory approach, developing children's fluency, reasoning and problem-solving. Numicon Big Ideas is a programme of additional sessions for small groups, focusing on key elements of the Primary maths curriculum for pupils not meeting age-related expectations in Upper Key Stage 2 or Key Stage 3 (aged 10 upwards). The Numicon Big Ideas programme can be run in 12 weeks and lays the foundation for success at Secondary level as well as in end-of-Primary assessments. The Numicon Big Ideas teaching manual includes a teaching guide explaining how to run the programme most successfully, initial assessment, 48 step-by-step teaching sessions, and photocopy masters to support delivery. Supporting apparatus for a small group is available in the Numicon Big Ideas Apparatus Pack, ISBN 9780198421399.
