Cylinder Blocks are a Montessori Sensorial material used to develop visual discrimination of size. These cylinder blocks are made by GAM (Gonzagarredi Montessori).
The series of cylinder blocks with the 10 knobbed cylinders are certified AMI-approved.
We recommend that you select the cylinder blocks that are appropriate for the child's age. If this is the child's first introduction to the cylinder blocks, we recommend you start at No. 1. These Cylinder Blocks were designed to be used in a specific sequence to maximize the child's learning.
