Lessons Mental arithmetic of decomposition of numbers

Summary of the program

In the mental calculation of numeric decomposition, you will be trained to further enhance the "sense of volume" and to become strong with numbers as it develops your number sense (the ability to decompose and compose numbers).

Once your ability to image numbers as volume and to decompose as well as compose those numbers to a certain degree, your further training to decompose and compose a number as it is will make you even stronger with numbers.
Once you become able to decompose and compose a number in your head, you will grow up with even higher level of your numerical sense. Let’s do the best.

Abilities which can be developed
