What test paper is better to buy for math in grade three?
Understanding does not mean that you can write, do and understand by yourself. It's because the teacher has finished the whole process, but it's not the same thing to solve the problem by himself. I suggest that you learn the basic concepts of the textbook firmly, and do the questions asked by the textbook vendor yourself, without looking at the answers or the previous examples, and then you can do all the questions except the textbook, with 40 points.
