Knobbed Cyclinders: Set of 4
Regular price
R 230.00
The set of four mini knobbed cylinders introduce the visual discrimination of size, they refine the child's perception of dimension and prepare for mathematics activities such as comparison, grading and seriation. The blocks provide a control of error and even a young child can use them successfully.
Each Knobbed Cylinder block differs as follows:
- Block One: varies on height and diameter, ie. the tallest cylinder also has the widest diameter.
- Block Two: variation is based on the diameter of each hole.
- Block Three: varies on height and diameter, ie. the tallest cylinder also has the thinnest diameter.
- Block Four: variation is based on the height of the cylinders.
