I learned that the child listened to you and understand you, you have to hold his hand. I contribute to the correct perception of information.
For example I have a brother. and every evening we had done his homework and that we do not love him the same way. he is very lazy with respect to learning, especially when it is necessary to write off.
I used a lot of techniques. For example. motivate him, saying if we will promptly do the lessons we played, it did not help. I played first and then sat for lessons, it helped only 10 minutes.
After I found out about this method, I will use it.
