Please note:
Montessori materials are NOT toys, but educational materials. Proper use requires appropriate training.
Montessori materials may contain small, rough, sharp, or other elements that could cause injury or damage if used improperly.
It may therefore only be used by children under the supervision of appropriately trained persons and in an appropriate environment.
Open the rail, arrange balls and visualise numbers and arithmetic operations. Discover the number structure up to 20 and the concept of addition and subtraction by sliding balls. By representing numbers linear, in a rail, the development of a mental number line is stimulated. Make smart use of the colour change (red/white): in this way pupils easily recognise anchors like 5, 10, 15 or 20, without counting.
