How to write electronic convention for primary school students?

If you need to use a mobile phone, you should do the following:

1: From Monday to Friday, students use electronic devices such as tablets, mobile phones and computers at home, which can only be used for study, but not for entertainment.

Students should finish their homework and do their own things when they rest at home on weekends and holidays. If they want to use electronic devices for entertainment, they need to communicate with their parents and agree that they should use them for no more than 30 minutes at a time and no more than 2 hours a day.

3. If students violate the above provisions in the process of using electronic equipment, parents have the right not to provide the use of electronic products, cancel the entertainment time of students' electronic products in the future, or reduce the frequency and time of use.

Students can't bring their mobile phones to school during class.

5. Don't browse unhealthy websites such as pornography, drugs and gambling.
