“Essentially, The Cylinder Blocks are a sensorial exercise in discrimination of size. However, it is also an important muscular activity because the Child grasps the little knobs with her thumb and the same two fingers that s/he will later use to hold a pencil.” A Parents’ Guide to the Montessori Classroom by Aline D. Wolf.
Sold as a set of 4 cylinder blocks, made from solid Beech wood. Each block has 10 holes for cylinders that look similar to each other, but vary in graduated differences of depth and diameter.
