First of all, it is necessary to listen carefully in class. Now it's usually an exam, and the teacher has an analysis after the exam. Ask the teacher and classmates what they don't know on the test paper (after the teacher analyzes it), and then record the key points. Copy the wrong questions (this teacher usually has a plan)
If teachers often take exams (about 2-4 in 3 days), there is no need to buy more papers to do, otherwise they will be distracted and will not improve much. If you have already bought it, do it when there are few exams. It is best to control the number of undergraduate papers within three a day. You can choose a topic to do your own paper, and generally you don't need to finish it all. ).
If you don't have time, recite the formula, turn over the wrong set of questions (write down the mistakes in the exam and answer the above) and try to understand each question. Try to think about those questions that are not too difficult, but I really can't think of them. Be sure to ask the teachers and classmates (usually tell them).
Primary school mathematics is to teach children a series of knowledge about number, four operations, the calculation formula of figure and length, unit conversion and so on through textbooks, which lays a good mathematical foundation for junior high school and daily life calculation. Frieden Noel, a Dutch educator, said: "Mathematics comes from reality and must be rooted in reality and applied to reality."
Indeed, modern mathematics requires us to observe the world from a mathematical perspective and explain the world in mathematical language. Judging from the mathematics learning psychology of primary school students, the learning process of students is not a passive absorption process, but a reconstruction process based on existing knowledge and experience. Therefore, learning while doing and learning while playing will make children learn more actively.
