At Sheen Mount we implement and follow the '5 Big Ideas of Maths Mastery'.  This approach is used throughout the school, based on the National Centre for Excellence in Teaching of Mathematics. These 'ideas' run throughout every Maths Mastery lesson (coherence, variation, fluency, mathematical thinking and representation and structure).
