Is the model solving method useful? What effect does it have?
Recently, I bought a high school mathematical model solving method for my children online, and the effect is OK. My child's math scores have not been very good. After watching the advertisements on TV, I bought a set of cards online for my children to remember and watched the CD-ROM, so that she could see the problem-solving methods that have been in it. I think she can solve this math problem now, and she is no longer afraid to do it.
