Mathematics learning in primary schools has always been a weakness of some children. Xiaoyou suggested that parents can find some typical test papers for their children to do. Doing problems can best reflect the real learning situation of children, and then according to the situation of children doing problems, it is convenient to find out the weak points of children's knowledge and do targeted exercises.
This issue of Xiaoyou provides you with a set of math test papers for grades 4-6. The questions in it are all classic easy-to-test and easy-to-mistake questions. Students can take it seriously and how many points they can get in the exam. At the end of the article, I sorted out the reference answers for you.
