As a very typical Montessori material, the brown staircase conveys the relationship between sizes in two dimensions. The set consists of eleven blocks of the same length, each changing in height and width by 1 cm. If the child arranges the steps correctly, they will have a perfectly harmonious staircase. As a positive side effect, the accompanying adult can enrich the structure of the stairs with word lessons, for example thick - thin, thick, thick, thickest, high - low etc.

Use, advantages, areas of application for this Montessori material:

• Correct construction of the stairs from all existing blocks

• Relating larger and smaller levels, naming them with appropriate terms

• Learn word lessons (thick - thin, high - low)

• Follow the order and practice

• Estimate conditions

• Montessori material for children from 3 years

Scope of the Montessori sensory material:

10 brown solid wooden cuboids from 20 x 1 x 1 cm to 20 x 10 x 10 cm

1 additional small cuboid, as a replacement and for measuring the step height.

Instructions for the Montessori material Brown Stairs

The ten cuboids are placed in a mess on the carpet.

The adult starts with the thickest cuboid, grasps it with one hand and places it in front of him.

The next thinner is placed to the right of the first. This is done up to the thinnest cuboid.

This also serves as success control. After the stairs have been completely laid, the adult takes this and places it on the next thicker one. It shows that the smallest cuboid is the measure of the difference in height between the individual steps. A cuboid in the staircase on which the smallest is placed must have the same height as the next one, then the staircase is correctly placed.

The blocks are shuffled again and now you ask the child to lay the stairs.

1. All cubes are mixed and placed on the carpet.

Please give me the largest cuboid (this will be put aside)

Please give me the smallest cuboid (will also be put aside)

Which is now the largest?

Which is the smallest?

2. When the stairs have been laid, you can use a small glass marble to check whether you have laid them correctly. To do this, the marble is placed on the thickest cuboid and with a little momentum, it then rolls down the stairs.
