The Mathematics curriculum at Kidbrooke Learning Centre aims to scaffold understanding of key concepts enabling students to confidently tackle complex mathematical tasks. In Years 7-9, students build on the success they have experienced from the SATs and/or 11+ exam experience to embrace more challenging mathematics. The focus is on deepening their mathematical reasoning on their way to starting a very demanding GCSE / Key Stage 4 Curriculum.

The introduction of ‘real life’ maths, the application of formulae to extended learning, the linking of concepts taught in mathematics such as exponential graphs to concepts in science such as exponential growth of bacteria and disease are some of the things introduced and explored at Kidbrooke Learning Centre. What is introduced in Year 7 is re-introduced in Years 8 and 9 but with more complicated concepts added and the challenges and expectations increases with every year.

Students are supported to embrace the GCSE / Key Stage 4 Mathematics Curriculum with the expectation of securing ‘easily’ a grade 6 in the final GCSE Summer exams.
