There are many traffic rules on the road. There are also many rules in the class. Classroom rules are important. They can make us stay safe and study happily in the classroom.

To keep safe, you mustn’t run or play ball games in the classroom because they may hurt you. You mustn’t fight in the classroom either because it is too dangerous.

To study happily, you should keep your desk clean and tidy. You mustn’t talk loudly in the classroom because your classmates need a quiet environment to study. Everyone should keep the classroom clean because studying in a clean place can make you happy.

Follow the classroom rules and they will be helpful to you.
