Abucus for children

My daughter learned Abacus and now she is a wizard in Math. I too am very much fascinated with Abacus. My daughter taught me Abacus. It is proven that when children use both hands to move the abacus beads to perform arithmetic calculations, there is quick communication between the hands and the brain that stimulates both the right and left hemispheres of the brain. This promotes rapid, balanced whole brain development. If a child starts learning the abacus before being taught traditional arithmetic, there is minimal conflict and the child will easily work within both systems.
