Pea has a passion for numbers for some time: the decimal system is demonstrated with this material!
This learning begins when the child has already mastered the first work on the numbers: count to 10
Nothing easier than handling 10 beads that make a strip 10, the 10 bars that make a plate 100, the 10 plates that make a cube of 1000, and from there the rest of the count will go to "fill", "dress" intervals of 10 to 20 (11, 12 ...) 20 to 100 (30, 40 ...) from 100 to 1000 (200, 300 ...). Pea will show you all this work very quickly ...
