Addition Strip Board
Your students practice addition tasks in the number range 18 with the Addition Strip Board. The transition from ten to ten is shown particularly clearly. The geometric representation of the arithmetic task makes it easier to solve the tasks.
Material according to M. Montessori
- 1 abacus
- 9 pieces of red stripes: number 1 to 9
- 9 pieces of blue stripes: number 1 to 9
A red stripe is laid out, e.g. B. the 7, then the blue stripe to be added is applied, e.g. B. the 5. The children can now determine the result by reading the number or by counting the boxes.
