Montessori students use a variety of hands-on learning materials that make abstract concepts clear and help the child to develop a sound foundation in mathematics and geometry.

By using concrete materials during the early years, the child can learn the basic concepts of mathematics and the relationship between numbers and quantities.

Mathematics activities are organized into five groups: (1) introduction to numbers; (2) introduction to the Decimal System; (3) introduction to tens, teens and counting; (4) arithmetic tables; and (5) abstraction.
