Our daughter is already 5 years old, and we have been taking smartum mental arithmetic courses for six months. We used to go to the early childhood development center, but now she has grown up, and I see that we need something more, because we study poetry in kindergarten for a long time, and we do mathematics and numbers without enthusiasm. These courses are based on teaching children to verbally solve absolutely any arithmetic problems. Our daughter, along with other children from the group, learns to count on Japanese soroban accounts, and then they imagine them and move the bones on imaginary accounts. With such a score, both hemispheres of the brain are involved, when, as with a normal score, only the left one is involved. Now our child has become free to count, subtract and add in her mind, she easily learns poetry, concentrates quickly and has become much more patient and persevering. All their classes are held in a playful way, we are given homework at home, which we do with the help of a specially designed computer program. Our coach checks them online and immediately sees which material the child has learned and which has not, and then corrects the training. We really like this learning option, and most importantly, the child himself enthusiastically rushes to classes.
