Math problems, students in senior two and senior three, not everyone can do. This kind of math problem is for children in Grade Two. I believe that such a teacher should have a way to make the children in grade two understand it generally, otherwise it will be illegal.

It is not advisable to only give children problems and point out their problems, and there is no corresponding method to keep up with them and no training is in place. It is even more undesirable to throw the problem to parents who have no teacher qualification certificate.

The textbooks in our country all put these abstract concepts of addition, subtraction, multiplication and division in the fourth grade, some in the last semester of the fourth grade, and some in the next semester of the fourth grade, which is in line with the law, the law of knowledge itself and the cognitive law of children, so it is also in line with the teaching law.

Unfortunately, there are too many illegal things at present! Some institutions actually teach preschool children to learn three-digit multiplication. Tossing children and parents, of course, some parents like to be tossed like this, so this practice is very marketable.

This is at the expense of children's childhood happiness and happy childhood, at the expense of children's all-round development, and with abnormal development instead of all-round development. In the whole primary school stage, children have two weaknesses, namely, abstract thinking ability and spatial imagination ability. The solution, I summed up as a general formula: turn the intangible into tangible, and then guide it step by step to the intangible; Turn abstraction into concrete, and then lead to abstraction step by step.

Specific to the topic mentioned by the subject, different teachers may have their own different solutions, and truly: everyone knows the second day of junior high school, and everyone knows it. When this happens, I will guide it around a big circle and try my best to treat both the symptoms and the root causes.
