Fun brain training for children! 

A program for children that improves intellectual capabilities with the help of an abacus. Addition, subtraction, multiplication and division with the abacus helps children make fast calculations and learn to manage numbers in a short time.  

Already in the first lesson children learn to use not only the physical abacus but also a mental one. This allows children to use both sides of the brain, which as a result improves the efficiency of the brain.
