Application In the field of education, from 5 to 12 year-old children both in traditional and special groups the last being taught on the basis of alternative curricula. Used for playful and spectacular maths education. Advantages The instrument allows children to internalize the external pictures of their environment thus helps to understand new relations, gain new knowledge, memorise and recall it.
