 Cylinder Blocks (חושים)

The Cylinder Blocks provide the first stage (introduction) of experiences in visual discrimination of size. Grasping of the knobbed cylinders indirectly prepares the child for writing by developing the three finger grip. They are made of solid beechwood that is finely finished for quality appearance and years of service. Recently re-designed, the block has slightly rounded edges and each cylinder is individually sanded and lacquered. Progresses in diameter from thin to thick.

The Constructive Triangles give the child
practical experience in plane geometry. They are called “constructive” because the child sees the triangle as the element which forms other rectilinear figures. The set consists of two rectangular boxes, one triangular box, one small hexagonal box, and one large hexagonal box, each containing triangles of differing size, shape and color.

The Geometric Solids introduce the child to solid geometry. The set contains one each of the following solids: cylinder, cube, ellipsoid, cone, sphere, squarebased pyramid, triangular-based pyramid, ovoid, rectangular prism and triangular prism. Also included are three clear stands for the curved-sided solids.

This series of prisms demonstrates to the child the change in width (breadth), while the length of 20 cm remains constant. Further practice with the Broad Stair indirectly prepares the child for concepts in plane geometry, area and volume. The hardwood prisms are crafted in precise progressions from 1 x 1 x 20 cm (thin) to 10 x 10 x 20 cm (thick).

The Knobless Cylinders are the final stage
(application) in the dimensional material where the child places in order the sets of
cylinders based upon his abilities to discriminate. The cylinders have
interrelationships in size that are revealed to the child as he works with the sets in combination. The Knobless Cylinders set
consists of 4 boxes, each containing 10 cylinders. The four sets are each contained in a separate beechwood box with the lid painted the same color as the cylinders.

This material is used to link the three dimensional Geometric Solids to their corresponding two dimensional plane figures. The set includes five plane figures with box.

Constructive Blue Triangles (חושים)

 The final stage in color discrimination is grading the shades of color. Eventually, the child will learn the terms connected with his visual discernment, i.e., dark and light and the comparatives and superlatives. The Third Box of Color Tablets contains 63 tablets representing nine colors in seven graded shades of red, blue, yellow, green, purple,
orange, brown, pink and gray.

This series of cubes develops visual discrimination of size in three dimensions. Exploration with this material prepares the child for mathematical concepts in the decimal system, geometry and volume. The Pink Tower consists of ten wooden cubes painted pink and graduated in increments from 1 cm3 (small) to 1000 cm3 (large).

The Sound Boxes develop auditory discrimination through exercises in pairing and grading a series of sounds.
This item consists of two sets of 6 sealed wooden cylinders containing materials that make a distinctive sound when shaken by the child. The cylinders are graded from very soft to loud.

The Number Rods introduce the child to quantity 1-10 and their corresponding number names. Through exploration withthe material, the child also develops
concepts in sequence of number,
combinations of 10 and basic arithmetic.
The material consists of ten wooden rods,
divided into units by alternating colors of
red and blue, progressing in ten equal
steps from 10 cm to 1 meter.

The Sandpaper Numerals introduce the
child to symbol 0-9 and their
corresponding number names. By tracing
the numerals in the style and direction in
which they are written, the child is
preparing for writing numbers. The 10
rough sandpaper numerals are mounted
on smooth green boards.

This Spindle Box provides practice in associating quantity and symbol for all the numbers 0-9.
The Spindle Box is crafted from solid beechwood with a natural finish. 45 loose wooden spindles are included with this material.

 An enjoyable counting activity that reinforces the sequence of numbers from 1 to 100. The Hundred Board is used by placing the wooden chips in sequence on the board. The material consists of 100 printed wooden chips stored in a wooden box with lid and a wooden board with 100 squares printed on it.

In the final stage of number work 1-10 the
child applies his skills in associating
quantity and symbol by identifying and
placing the numerals in their proper
sequence and then associating the
corresponding amount of counters
beneath them. The pattern in which they are placed is used to introduce the concept of odd and even. The set includes
a box with lid and two compartments
containing 55 red wooden counters and
red wooden cut-out numerals 1-10.

This two-compartment box with lid contains plastic chips, one set with equations printed on them and one set with the answers to be used with the Addition Working Charts. All the equations and sums for the addends 1-9 are included.

Through activities with the Dressing Frames, the child develops coordination, ability to concentrate and skills of independence. The Dressing Frames are constructed of hardwood with durable material securely attached for workability and longevity.

The Large Fraction Skittles represent divisors of 1⁄2, 1⁄3, and 1⁄4 and are used with the Fraction Circles to work equations in division. The set is constructed of hardwood in different colors.

With this globe, the concept of continents is reviewed with the child and the continents are named. The activities with the globe lead to work with the puzzle maps.
