What do asynchronous counting on soroban, mental counting, and kinesiological exercises do? This motor technique promotes the development of interhemispheric connections, including the corpus callosum, synchronization of the work of the hemispheres occurs, new neural connections are formed, and mental activity improves.
The technique allows you to identify the hidden abilities of the child and expand the boundaries of the capabilities of his brain.
Certain facts. Continue reading “The child’s mind is on his fingers”
Mental arithmetic history
According to one version, the beginning of its existence can be considered the invention of an abacus of Chinese origin (suanpan) more than 5 thousand years ago.
