In addition to this information, have a look at the main Montessori page (which has some general drawings and links to sites)and in particular Shu Chen Jenny’s page which describes them excellently.

“Dr Montessori designed concrete materials to represent all types of quantities, after she observed that the child who becomes interested in counting likes to touch or move the items as he enumerates them. In a Montessori environment, a child not only sees the symbol for ‘1’, ‘1000’ or ½, he can also hold each of the corresponding quantities in his hand.”
‘A Parent’s Guide to the Montessori Classroom’ p.39 – Aline Woolf
This is a list of some of the Practical Life and Sensorial activities that will have a great impact upon the child’s further explorations into mathematics. They are a fundamental part of the Montessori Curriculum and should not be rushed through in order to get on to either the Maths or Language material. The more experience the child has of these exercises, the easier their understanding and cognitive development.
Practical Life
Name of Activity
|
Preparation for…
|
Sorting objects | Classification |
Pegs | Order and sequence |
Threading | Order and sequence |
Folding mats | Fractions |
Weighing | Weight and concept of ‘equal’ |
The exercises of Practical Life all encourage concentration, order, independence and self-correction. All of this will be an important basis on which the child is prepared for mathematics and problem solving.
Sensorial
Name of material
|
Preparation for…
|
Knobbed cylinders | Dimension order and shape |
Pink Tower | Dimension, order, metric size, height |
Broad Stair | Width, size, order, shape |
Long Rods | Length, order, direct preparation for Number Rods |
Knobless Cylinders | Dimension, order, height |
Baric Tablets | Weight |
Stereognostic materials | Size, 3D shape, weight, sets, order, classification |
Geometric Cabinet | Plane shapes, concept of concrete to abstract ideas & representations |
Geometric Solids | Sets, shape, size, movement |
Binomial Cube | Shape, problem solving, algebra |
Constructive Triangles | Shape, size, angles |
Tessellation | Area, shape, size |
