MATHEMATICS

MATHEMATICS

Maria Montessori believed that Mathematics should be considered as a special kind of language. It is very clear and concise that way of communicating with others in a particular area.
Dr. Montessori stated that man is born with a “Mathematical Mind.” She took the term from Pascal, the French philosopher and mathematician, who said that “man’s mind through certain tendencies and sensitive periods as well as through the fact that the young child needs to understand his/her environment in a logical manner. In order for humankind to develop and progress he/she must acquire the ability to discriminate in all areas.
Maria Montessori approached the introduction of mathematics in the same way as the other materials which she introduced to the children. She selected an abstraction i.e., number and turned it into something concrete, a “material abstraction “e.g., the Number Rods which the child worked with until he/she had grasped the concept and was able to use it.

Equivalent Figure Material

(1 review)

The Equivalent Figure Material is an important component of the Montessori educational approach, designed to introduce children to the concept of equivalence that leads to the discovery of area and theorems.

By manipulating the pieces and observing their relationships, children can discover that shapes with different sizes can still be considered equivalent. This understanding lays the foundation for later mathematical concepts such as fractions, ratios, and proportions.

The Equivalent Figure Material consists of 13 green metal frames with bottoms and red insets.

Instrument For The Measurement of Angles and The Centisimal Frame

Set of 2 black wooden plates measuring 14 x 14 x 1 cm.

The Instrument For The Measurement of Angles is calibrated in 360 degrees for positioning a fraction piece from our 4.45 Fraction Circles to demonstrate how angles are measured in degrees.

The Centisimal Frame is calibrated from 0 to 100, and is used with 4.45 Fraction Circles to demonstrate how fractions may be reduced to decimal fractions.

Fraction Pie Puzzles

Leveled puzzle cards teach parts of a whole, equivalencies, common denominators, and multiples.

Each Fraction Pie Puzzle is a puzzle and a conceptual fraction lesson, all rolled into a fun activity.

Select a card, place the starting pieces, and then complete the circles with the remaining fraction pie pieces. Will one-third solve the puzzle? What about 2 one-sixths?

This kinesthetic way to reinforce basic fraction concepts teaches children how fractional parts make up a whole and about equivalencies, common denominators and multiples.

Leveled from easy to difficult and self-correcting, the puzzles are perfect as a small group or center activity. It's an entertaining way for children to challenge their brain and understand fractions.
