GAM 0-3 Cylinder Block 4

In Block 4 the cylinders change in height, growing from short to tall, while the diameter stays constant. Isolating one dimension helps a child focus on a single change and read differences in height by eye.

The Cylinder Blocks introduce the first stage of visual discrimination of size. A child removes each knobbed cylinder, studies the graded socket and returns it to the matching hole, learning to compare dimension through repeated handling.

Control of error is built into the wood. If a cylinder is placed in the wrong socket it will not sit level, or a cylinder will be left over at the end, so the child sees and fixes the error without an adult.

The four blocks each isolate a different change in dimension. Block 4 varies height alone, while /products/gam-0-3-cylinder-block-2 varies diameter alone. Working across the set builds a full sense of size before the child meets the knobless cylinders.

Yes. Each cylinder has a small knob gripped with the thumb and first two fingers. This pincer hold is the same grasp used later for holding a pencil, so the work quietly prepares the hand for writing.

Wipe the beechwood block and cylinders with a soft dry cloth and keep them away from water and strong sun. Store the cylinders in their own sockets so none go missing and the block stays complete.
