MATHEMATICS

Ten metal circles, one undivided, the others divided into two to ten equal parts.

All insets are painted red and fitting into green frames.

The set consists of 4 metal frames with bottoms.

Make an analytical study of triangles.

Insets are equilateral triangles divided into 1, 1/2, 1/3, and 1/4.

Frame size: 5.5 x 5.5 inches.

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.
 

This material represents 3 cases of the Theorem of Pythagoras.

The material consists of 3 green metal plates with bottoms, and blue, red, yellow and white inset pieces.

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.

The red whole and cut-out labeled circles are stored in a wooden box with 10 compartments.

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.

Includes:

The Decimal Fraction Material is used for the introduction of decimal number formation and for performing the operations of addition, subtraction and multiplication with decimal and whole numbers.

A beech wood box containing yellow, square rules figures for the area exercises.

The complete set includes a wooden stand, a transparent plastic ruler, and a clear board. 

This set is used for plane geometric form exploration that facilitates in the measurement of height.

It is designed for use with the Constructive Triangles and the Yellow Triangles For Area, with measurements in centimeters.

This material is used in the elementary classroom for the study of lines, measurement of angles, and the construction and analysis of plane geometric shapes.

Boost early geometry, critical thinking and fine motor skills with the help of the included Challenge Cards.

Use the 6 different stick-and-ball shapes to craft 2D and 3D shapes.

Includes 58 pieces, 10 Challenge cards and Activity Guide.
