Montessori classroom works are displayed in an intentional and sequential order so that children’s skills are being built deliberately to ensure success in a more advanced skill set. Montessori intended for children to explore the Practical Life and Sensorial areas of the classroom in order to learn pre-mathematic skill sets such as order, logic, sequence, and measurement. Eventually, children are ready to explore more abstract thought beginning with quantity. Montessori encourages children to learn through their senses by manipulating materials—and mathematics is no different. By working with the concrete materials Montessori designed, the children can absorb the basic concepts of 1 to ten, the teen numbers and on into the hundreds and thousands. Making the transition to the abstract is effortless because the base has been established through the concrete nature of the materials.
