Developmental recipes can be purchased either together with the course, or completely independently. They include 65 lessons on logarithms, neurography, finger games, listening to music, and drawing. Approximate duration of training: from 2 to 5 months. Depending on the intensity of filling. Methodological explanations are provided for each lesson. The copybooks reinforce the material of the video lessons of the course and provide a deep immersion into the materials. After each video lesson of the Ensemble course, you are given homework with numbers to complete. It is advisable to do them, but not obligatory. However, my experience shows that children study with great interest according to copybooks, even without the help of their parents.
