With the addition box, children get to know addition problems in a particularly easy way. Two numbers from the number range 1 - 18 are added up at a time. The control panel in the addition box enables simple self-control. The child takes a task tile, e.g. 4 + 7, and looks for the corresponding result on the solution tiles. The tasks can also be supported with pearl material.

Instructions for the Montessori addition box
An adult puts the box with the task and solution tiles in front of him. He takes out the
task cards and sorts them according to the first number (1 + 1, 1 + 2 ...... 1 + 9 = 1 pile; 2 +1,
2 + 2 ..... 2 + 9 = 1 Stack.....).
Then the number plates are pre-sorted according to the value. This makes
orientation easier for the child later.
The solution card is first placed face down on the table.
Now the task cards are processed one after the other. When the child is working with the
material for the first time, it may make sense to work through the tasks in order (1 + 1; 1 + 2; 1 + 3;
1 + 4 ...). The adult does the same during the introduction of the material. After seeing the
Has assigned solution tiles to the tasks, he takes the solution board and checks
by reading whether he has solved the tasks correctly.
Then the next batch is processed.
