The cylinder block is a learning tool intended for children aged 3 to 6. Its purpose is to develop the child's visual acuity by allowing them to distinguish and categorise different sizes. To do this, the wooden block contains 10 green cylinders of varying dimensions. As the height of the cylinders increases, their diameter decreases.
In addition to its usefulness for the visual discrimination of sizes and the perception of dimensions, the tool also helps to learn adjectives such as small, large, tall, short, wide, thick, thin, or equal. The cylinder block is one of the most versatile tools of the Montessori method. Indeed, beyond the applications mentioned above, this material can also introduce the child to geometry.
