In our class, when a child of two and a half comes, he already posses the MATHEMATICAL MIND.
"The Mathematical Mind’ refers to the unique tendencies of the human mind", Maria Montessori . She was familiar with Blaise Pascal, a French philosopher, physicist, and mathematician, who theorized that “man’s mind was mathematical by nature and that knowledge and progress came from accurate observation” (The Absorbent Mind, 17, pg. 169).
So a little child starts exploring things in his environment ,getting the idea of shape, size, length, height, colour, sorting, and dimensions .
Now the concept of TENS is being learned using the same GOLDEN BEADS and then making the exact numbers for them.
This is another Hands on material called "Addition Strip Board" which stimulates the child's mind to make his own Addition Table using this simple but brilliant Montessori material.(my children love this material and learn all the basic Addition tables not by memorizing but by doing it by themselves).
These kids are doing the Addition Table of 3 by discovering on their own .
This child is adding using the STAMP GAME. Typically it is used by children (ages 4-7) for both static and dynamic addition, subtraction, multiplication and division. After being introduced to the process of the decimal system using the golden bead materials, the Stamp Game provides opportunities for individual practice in the operations of addition, subtraction, multiplication, and division. In a step towards abstraction, the quantity and symbols of the decimal system are combined and represented by each stamp.
