Mathematics in the Golden Grove School classroom gives the children the background and history of mathematics. It allows children to move through the curriculum in a logical systematic way, beginning with concrete materials and working towards abstract ideas, concepts and operations which build upon each other.

The mathematics lessons and practise work rely heavily on the Montessori mathematics materials that are orderly, attractive, empowering and engaging. The mathematics curriculum includes the teaching of number identification and order, place value, addition, subtraction, multiplication, division, fractions and decimals. It also has concrete materials that give hands on experiences with algebra, measurement, geometry, shape, position, orientation, statistics and probability.
