I find it a good advantage that it is possible to organize group activities with a large number of children using a small number of sets. And also high quality of the manufacture of the kit. The set will work for a long time. Of course, it’s great that there is no need for computers. Teacher can perfectly combine physical activity, mental and creative work in accordance with the principles of STEAM education. Recommendation: to come up with a more convenient box for storing parts, which could be used in the lesson as an organizer, and not transfer blocks to other containers.
