From the youngest in the Pre-Prep department through to preparation for the higher-tier papers in Year 8, children are encouraged to think for themselves and present material which is well-presented and accurate in content. To this end, great emphasis is placed upon a thorough knowledge of tables, number bonds, and mental arithmetic and its use of solving problems.

A combination of new and traditional maths is taught with the syllabus being based on the attainment targets of the National Curriculum. The majority of pupils work at an even higher level in order to achieve the excellent results that have been achieved in Common Entrance over the past few years. Maths is set by ability from Year 4 and taught by mathematics specialists from Year 5. This enables teachers to address specific needs and stretch each child individually. Extra assistance is offered to those children throughout the school who require additional time to master the basics with all children being encouraged to seek advice and assistance at all times to further their mathematical studies.
