Set of 11 numbers made of RE-Wood. The numbers help you visualize math. By stacking a 2 and an 8 you get 10. If you stack 2 and 8 your tower will be as high as the number 10. The set contains 1 x 1, 1 x 2, 1 x 3, 1 x 4, 2 x 5, 1 x 6, 1 x 7, 1 x 8, 1 x 9, 1 x 10 and allows to stack several times the value 10 with different towers. The value of the stacking numbers (made from solid material) corresponds to the height in centimeters. All numbers are 4 cm wide and 3 cm deep.

You can also do other calculations, you can for example make 3 towers of 20. By counting/stacking up the numbers you visualize the counting and see that you can make 10 or 20 combining different numbers. In our school, they call that the friends of 10 :)( 2 + 8, 5 + 5, 6 + 4 etc) If you are able to learn them by heart you have the best start for any math assigment.

The numbers are made of RE-Wood which is a new material made in Germany of wood waste and a natural binding material. RE-Wood is very strong and safe, it is approved to be used in primary schools, biodegradable and can be washed.

The set comes in a natural cotton bag.
