The pearl material is the arithmetic material badly. The different numbers of pearls and the different colors each represent the value of a digit. Numbers are shown tangibly and differentiated by colors.
An example: The child assigns the pearl bars to the correct number. The 10-point transition is particularly interesting. This automatically adds 10 + the corresponding number.
Application, advantages, areas of application for this Montessori material:
- Getting to know the numbers up to 20

Instructions for the Montessori pearl staircase
An adult takes the red one-pearl and holds it with the index finger and thumb of the left hand.
With the index finger of his right hand, he runs over it from left to right and counts aloud one.
Then he hangs them in their place on the hanging bar.
This continues up to the ten rods. It is always counted from left to right.
For the numbers on the second hanging bar, two pearl rods are required for each number to be displayed. This is eleven. We need ten and one.
One or more bars is/are removed and put back in the right place by the child.
Which poles do we need for the 13th?
