Cylinder Block No. 1

Cylinder Block No. 1 is designed to help children develop visual discrimination of size and dimension. It is an essential tool for developing a child's ability to discern differences in size and dimension through tactile exploration. The varying heights and diameters challenge children to match cylinders to their corresponding holes, improving hand-eye coordination. It consists of a wooden block with 10 knobbed cylinders varying as follows: diameter decreases, height decreases.
