To sharpen a child's visual discrimination of graduations of size in a series.
To develop fine muscle coordination and extended concentration through comparisons of series of different cylinders
To teach the concept of size and scale
To develop the child's visual perception of dimension.
To develop the child's coordination of movement and fine motor control.
To prepare the child, indirectly, for mathematics by giving the child experiences in comparison, grading and seriation with varying combinations of forty cylinders.
To provide basic language -important in mathematics.

Exercise

First show the child how to carry the box of cylinders to the table, holding with both hands.
Sit beside the child and place one box of cylinders in front of the child.
Show how to take the cylinders out from the box by holding them at the top with 3 fingers; giving them the demonstration using your thumb, index and middle finger.

The child to work with these boxes should have had practised with four blocks of knobbed cylinders which helps him understand the sizes and their arrangement. The child’s practise over pink tower, brown broad stairs and long rods helps him to imagine varied patterns which now are part of his creative. This lays the foundation for working with geometric solids which is related to enhancement of muscular memory. The child’s imaginative and creative skills enhanced here lay a profound platform to work with tessellation material, where the child works upon patterns.
