At around four years of age the child is ready to experience the Montessori mathematical materials. One new concept is taught at a time starting with numbers 1 to 10, proceeding on to the decimal system, counting and the four rules (addition, subtraction, multiplication and division). Uniquely designed materials provide concrete ideas and sensory experiences of these concepts. Gradually the child can move confidently towards the completion of abstract mathematical problems. Montessori educated children leave Great Beginnings with a great love of numbers and mathematics.
