The Montessori knobbed cylinders introduce young children to changes in dimension.
Of the cylinders, Maria Montessori said:
"The aim is not an external one, that is to say, it is not the object that the child should learn how to place the cylinders, and that he should know how to perform an exercise. The aim is an inner one, namely, that the child trains himself to observe; that he be led to make comparisons among objects, to form judgments, to reason and decide; and it is in the indefinite repetition of this exercise of attention and of intelligence that a real development ensues."
