0-3 Cylinder Block #3 Inverse changes of Height and Diameter

(Bloc à 3 cylindres)

The Cylinder Blocks introduce the child to the first stage of visual discrimination of size. Cylinders diminish in height yet increase in diameter from tall to short and thin to thick.

The 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.

The child initially works on one block at a time, later the sets are combined and the interrelationships in size are experienced.

Use language such as 'taller', 'smaller', 'heavier', or 'lighter' to compare and describe the shape and size of solids.

This is an educational product and is only to be used under the supervision of professional trained adults in a school environment.
