The author starts from the assumption that today's children face such a range of stimuli and various temptations that it is increasingly difficult for them to perceive a specific topic, concentrate on teaching, and manage homework smoothly and without unnecessary delays. Research has shown that around 40% of children have serious concentration problems. However, without concentration, success is not possible. This guide clearly shows what is actually happening in a child's mind, how to recognize deficiencies in concentration, and how parents can help their children to concentrate better – whether by creating the right environment, ensuring sufficient physical activity, or through practical exercises. A test, divided by age groups, will help parents determine where their child's potential lies and what their weaknesses are.
