Addition Strip Board
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.
The material gives insight into the nature of the addition. The child recognizes, practices and memorizes all combination tasks up to 18. The vertical red line behind the number 10 tells you that all quantities beyond 10 are to be broken down into tens (10) and one or more units.
