The Montessori Math Starter kit 1 consists of:
- the addition table with the box of red and blue rods. The vertical line on the board, which is more pronounced at the 10, visually and clearly signals to the child the passage of numbers through the 10.
- the control board;
- a bag with all the addition combinations up to 18. The maximum number is 18 because it is the maximum number that can be combined with the largest rods: 9+9. The number of vertical boxes is 10 because, in the base-10 system, this is the maximum number of possible combinations.
This material allows the child to practice the sequence of addition and subtraction combinations in a pleasant and independent way, thus beginning the memorisation process. It is a very useful psycho-arithmetic material for training the mathematical mind.
The e-book presentation is included in the kit.
