The fifth grade refers to the senior stage of primary school. Students in the fifth grade of five-year system have to face the "junior high school" exam, study hard and review what they have learned before. Students in grade five of the six-year system should prepare for junior high school in grade six, so they should also study hard and prepare for junior high school.

The fifth grade is the most important grade in a five-year primary school. Because of the "senior high school entrance examination", fifth-grade students should study hard and strive to do well in the exam.

The subjects studied are not much different from before, including: Chinese, mathematics, English, science, morality and rule of law, sports, music, art and information technology.

In the autumn of 2008, readers often have some questions when buying or using one lesson and one practice. Here are five focused questions that need to be answered:

1. What are the new changes in "one lesson and one practice"?

The column setting of "one lesson and one practice" in some grades of mathematics, Chinese and physics has been greatly adjusted, which has broken the previous unified column setting form regardless of grades and disciplines and is closer to teachers' teaching and students' learning process. Continue to add interesting sketches and network problems to the book cover.

All the staff of "one lesson and one practice" are rooted in "trying to improve a little more for all the children in Shanghai". The setting of each exercise has been carefully thought and edited by the author to form an orderly and effective training system, so as to make students practice the least topics and achieve the best learning effect.

2. Which books in this series are equipped with detailed e-books to answer the exercises? How to get e-books?

In order to facilitate students' self-study and parents' guidance, we have made detailed answers to the exercises of grade six, seven and eight mathematics (trial version, enhanced version), grade eight and nine physics (trial version) and grade nine chemistry (trial version) and compiled them into e-books. As long as we log on to the website of "one lesson and one practice" and fill in the correct grade and email address, we can get the exercises of this grade for free.
