What is the basis of the mathematical system according to Montessori?

The basis of the mathematical system according to Montessori is rooted in the decimal system, which is fundamentally based on the number ten. This reflects how the Montessori approach emphasizes the understanding of numbers and their operations through experiences and materials that correspond to the decimal system.

In a Montessori classroom, children encounter materials that help them grasp concepts of value, quantity, and place value by working with units, tens, hundreds, and thousands, all organized around the base ten. This system not only fosters a solid understanding of arithmetic operations but also encourages children to appreciate the patterns and relationships inherent in numbers.

Other numerical bases, while they can be part of mathematical learning, do not have the same foundational importance in the Montessori material and pedagogy, as the focus is specifically on the structure and operations surrounding the decimal system. This focus on ten allows children to develop a more intuitive understanding of math that is practical and applicable in everyday life.
