Knobless cylinders

The Knobless Cylinders are the final stage in the dimensional material where the child, based upon his ability to discriminate, places the individual sets of cylinders in the correct order. Each set of 10 cylinders are contained in a separate beechwood box with the lid painted the same color as the cylinders. Each box contains ten cylinders, useful for educating the eye about size and learning the concepts of: large - small; large - fine; high - low; high, fine - low, wide.

The game-work, which corresponds to the solid joints, is used to discriminate the graduated differences of the cylinders. The coloured cylinders are a very valid and amusing material useful for educating the eye about dimensions. Thanks to the possibility of being able to touch the cylinders with ease and to be able to graduate them, the concepts of large - small (yellow cylinders: vary in height and diameter); large - fine (red cylinders: vary only in diameter, which decreases regularly); high - low (blue cylinders: vary only in height); high, fine - low, wide (green cylinders: have inversely proportional dimensions and vary in both height and diameter) are concretely learned. The cylinders of all four boxes can be used at the same time, for example, to build towers or to experiment with different combinations that help to distinguish and classify degrees of size.

Measures

Dimensions of each box: 15.5x13x7 cm. Size of blue cylinders: same diameter (2.5 cm), different heights (5 cm to 1 cm). Size of red cylinders: same height (5 cm), different diameter (from 5 cm to 1 cm). Size of yellow cylinders: height and diameter gradually decrease in synchrony (height and diameter vary from 5 cm to 1 cm). Green cylinder size: height and diameter change in opposite directions (height and diameter vary from 5 cm to 1 cm). Pieces: 4 boxes + 40 cylinders

Sensory material: made up of a set of objects "grouped according to a certain physical quality" - weight, temperature, size, shape, colour, sound, etc. - which are then used to create the sensory experience. - Refining the perception of each sense encourages exploration and knowledge. From around 36 months. The boxes and cylinders are made of wood. The cylinders and lids are red, blue, yellow and green. The senses, 'windows on the world', accompany development. The coloured cylinders are useful for visual dimension education.
