Description
This activity improves the Child’s ability to discriminate between size, height and volume.
The Knobless Cylinders, consist of 4 sets of 10 colorful cylinders:
- Red – Cylinders vary in height and diameter
- Blue – Cylinders vary in height and diameter
- Green – Cylinders vary in diameter
- Yellow – Cylinders vary in height
Purpose
- learn how to grade by size
- train the eye to perceive fine differences in dimensions
- to recognize differences and similarities, (when using more than one set)
- improve hand-eye co-ordination of movement
- improves vocabulary
- The direct function provides the Child with an opportunity to hone their discrimination of size, height and volume. Together with the knobless cylinder cards, the Child uses his own visual ability to discriminate as a control of error.
- Each set has 10 cylinders, of a different primary colour. The lid of the beechwood box is the same colour as the knobless cylinders.
