• Math in the MSOSV Kindergarten Year

    Let’s begin with the absolute genius of Dr. Maria Montessori and her son Mario who developed the Montessori math materials.

    Over the years, there has been a consistent message from adults, either parents or educators taking the Montessori math component of the Montessori Teacher Education formal training.

    “I wish I had Montessori Math when I was a student”

    How is Montessori math different from traditional math?

    Traditional schools offer mathematics in an abstract format with the, group of children moving through the prescribed curriculum together. The MSOSV Montessori Guides present math with concrete, manipulative material. The student is presented the materials, as he or she is developmentally ready.

    “In our work, therefore, we have given a name to this part of the mind, which is built up by exactitude, we call it the ‘mathematical mind.’”
    – Dr. Maria Montessori

    The Foundation – Concrete Materials

    The Montessori mathematics are taught in a sequence starting at age 3:

    • Counting (from 1 to 10, 10 to 90
    • Linear 1 to 100 and 1000
    • Skip-counting as an introduction to multiplication)
    • Place value to four digits
    • Number operations (addition, subtraction, multiplication, division)
    Math with the Montessori Kindergartener

    At MSOSV, we maintain mixed-age classrooms. This means that any child who is ready to receive a new, more advanced math lesson, will have the opportunity to do so. This applies to any of the materials listed above. It is not uncommon for an older student to work alongside a younger student showing what they know. Teaching a friend to do a new lesson is a reinforcement of the lesson itself.

    There are, however, a few exceptions. We reserve some of the more abstract concepts for the kindergarten year. These lessons are taught in small groups with individual practice to follow:

    • Time – introduction to the clock and telling time to the hour and half-hour
    • Money – identifying the different coins and bills and learning their value and practice counting money
    • Measurement – learning how to use a ruler and tape measure to measure inches and feet
    • Temperature – understanding the thermometer and how to track the weather
    • Calendar – learning the days of the week, months of the year, and seasons in order

    Advantages the MSOSV kindergarten students have upon graduation:

    • The MSOSV kindergarten students have learned many mathematical concepts and math facts typically only taught in 2nd or 3rd grade
    • There is an enjoyment, a love of learning math, that they will carry with them into their elementary years and more
