It seems a good idea to give them homework for weekends. But I honestly believe that what should be reforming is the educational system, which is very bad in most countries. It must be educated for life, and not for children to learn to repeat what appears in a book.

I was a teacher for 1 school year, and innovated in my method. I gave computer classes, I do not study teaching anywhere, and yet they gave me the prize to the honorary professor of the year. My students loved me, to the point that even today I keep contact with them after about 20 years. My teaching method was based on learning playing, and I didn't even need to send them tasks for their homes because they themselves surprisingly worried about learning the lessons to continue moving forward in the game that I proposed in class.

That is why I say that what is needed is to change the teaching method, and if that is done, they will surely have very good results 😀
