The Knobbed Cylinders are a Montessori Sensorial material, designed to assist children in making distinctions in their immediate environment. This material primarily engages the senses of touch and sight. The material is comprised of 5 different cylinders with ‘knobs’ used to hold each object using the pincer grip. Each cylinder fits into a specific hole on a solid block of wood. There are four different variations of the Knobbed Cylinders, allowing children to challenge different perceptions of preliminary mathematical concepts, such as weight and size. Each Knobbed Cylinder block differs as follows:- Block One: varies on height and diameter, ie. the tallest cylinder also has the widest diameter.- Block Two: variation is based on the diameter of each hole.- Block Three: varies on height and diameter, ie. the tallest cylinder also has the thinnest diameter.- Block Four: variation is based on the height of the cylinders.
