On the issue of Wang with the use of the Beijing Normal University version of the experimental teaching materials on the sixth grade of the children together to review the semester of this knowledge, this issue please use the Beijing Normal University version of the fifth grade experimental teaching materials on the books together with the king Teacher to review the knowledge of this semester to learn it.
