My baby has been in a big class since he was four years old, but we have no homework when we come home from kindergarten, and even if the children don't learn, any early education is deceptive! There is no need to learn so early, because children have to go to preschool in primary school. Now that my child is in the second grade, I think it's good to learn something. A little behind those preschool classes that began to read, recite poems and learn abacus at the age of three or four. By the beginning of the first year and the next semester, there is no difference at all! Copying pinyin at such a young age, the teacher is really black! Kill children's imagination and creativity!
