Montessori cylinder volumes and weights box

These wooden weight boxes will develop mathematical and geometric logic as well as thinking in your child by teaching him to count thanks to the number of holes in the shapes and by teaching him the geometric shapes as well as to recognize them.

It will develop your child's cognition by mobilizing the learning of the representation of quantities, the child will work on the notion of physical representation through the quantity of stacked piece.

This toy will develop your child's motor skills as he will have to make the connection between the movement and the flexibility of his fingers when he pinches the grip of the cylinder with the coordination of his eyes, which will develop his sense of touch, his observation and analytical skills as well as abilities.

When offering weights to the child, always verbalize the goal. Example: "I will show you how to differentiate between weights". It is best to start with box A first, then introduce B, C and D. You can do the following:

1) Installation and preparation: Sit on a mat and ask the child to fetch only one box of weights to start, which allows him to develop the mastery of the gesture and inhibit distractions on the way (development of inhibitory control), in the event of an obstacle, it allows to develop flexibility.

2) Name the material: The adult names the "cylinder" so that the child assimilates what it is.

3) Present the object: Make an individual, exact, logical and uncluttered presentation of each cylinder.

4) Insertion of the cylinders into their base by sight: At the beginning, the adult should slowly show how to remove each cylinder from the larger box to the smallest by placing them on the carpet then he replaces them in their respective hole in the box. The child then tries. The adult can introduce the toy with a short story "The cylinder needs your help to get out of its house in order to go for a walk on the carpet" or "The cylinder would like to go into his house but he does not know the way , can you help her? ". Variation: Once the child has mastered all the cylinders of the 4 boxes, it will be possible to mix the cylinders of two boxes (A + B or A + C or B + C) and the child will have to replace the cylinders in their base respective. Repeat the exercise by mixing three boxes (A + B + C or B + C + D or A + B + D or A + C + D) then the four boxes (A + B + C + D).

5) Check errors: The adult must insist on checking the error, that is to say that there is has just enough space to insert a cylinder into its base, there should be no space left inside the cabinet hole. Then the child checks it himself. If he made a mistake when inserting the cylinders into their base, the adult then promotes self-correction without negative discourse about what the child did.

6) Inserting the cylinders into their base by touching: This process should be done when the child is comfortable with the different cylinders . The child is blindfolded and must return the 5 cylinders from a box to the base.

7) Learning weight adjectives: The child will learn the adjectives "light" and "heavy" or even "small" and "big" by comparing cylinders of different weights.

8) Learning superlatives and comparatives: By analyzing the different weights between each cylinder, the child will be able to introduce in his vocabulary "bigger", "Lighter", "just heavier" or even "just smaller".
