The LAB Maths department’s guiding principle for curriculum intent is as follows:

  • To provide the highest quality education in mathematics that prepares all students for future learning or employment.
  • To ensure that all students receive a knowledge rich education in mathematics rooted in conceptual understanding, reasoning, communication and language and problem solving. 
  • For all students to recognise the interconnectedness of mathematics and to have an appreciation for both its utility and its beauty.
  • The maths curriculum builds iteratively in order for students to build an extensive knowledge base at Key Stage 3 in preparation for Key Stage 4. All students will experience the main pillars of mathematics: number, geometry, algebra, ratio and proportion, probability and statistics.
