The fact that many children do not want to or are lazy to do lessons is completely not surprising. Adults can also remember themselves in childhood and should understand that they themselves were the same: I wanted to take a walk, do something else, but not boring lessons. Your task as parents is to find a special approach to your child and force the use of small forces to engage in lessons.
First of all, forget about the fact that the child needs to be punished: this is the most extreme measures and, as practice shows, not the most effective. First you need to talk with your child and try to explain to him how important it is. But, as a rule. Such conversations lead to zero, because children do not understand this because of their age.
The most optimal option is to influence the child with some measures that each parent must choose himself, just like the way to use them. Try to set the child the conditions from which he cannot refuse. Only all this should be non -violent in nature, otherwise it will lead only to conflict situations that should be avoided at any cost. You can, for example, set a goal for your child: you will give him something or buy him in the future, if he is responsible for doing lessons. Of course, this will not be chocolate, but something very important and significant for your child.
