One of the beautiful aspects of the Montessori Sensorial materials is extensions. With those children can put into practice their ability to grade and discriminate materials by width, length, size. From my experience, children master the Pink Tower, the Brown Stairs, the Red Rods and the Knobless cylinders very shortly after the initial demonstration. Sensorial extensions provide multiple opportunities to revisit these materials over and over again. Children create interesting patterns, stretch their imagination and usually work in a small group of peers which is a wonderful way to practice sharing and collaboration.

Here is Italian Montessori blog post (in English) that demonstrates numerous extensions for working with the Pink Towers and Brown Stairs which includes free printables.

Children often enjoy creating forms and shapes with the Constructive Blue Triangles. Montessori Constructive Blue Triangles Activity Set is the post written by the Helpful garden who kindly included their free printables. Montessori For Everyone also share their free extension printable here

Montessori Services offers Sensorial Cards. These cards provide an extension to activities using the Brown Stair, Pink Tower, Knobbed or Knobless Cylinders. By matching the parts of the apparatus to corresponding base cards, children refine visual discrimination of size. By comparing solids and planes, the child’s perceptions become more abstract.


Montessori Services have a wonderful series of Sensorial materials that I decided to include here. I think they can be a useful addition to the Sensorial area in the classroom.
