As part of the math curriculum, focusing on the understanding of numbers, counting skills, number work, measurement, fractions, simple addition, subtraction, multiplication and divisions is crucial to a child’s development of numeracy. The Montessori mathematical materials isolate each concept and introduce it to the child in a tangible form using manipulative equipment. Children first learn to associate each numerical symbol with the proper quantity. The child progresses one step at a time from a more concrete concept to a more abstract understanding of the concepts of arithmetic.
