Ron Clark is the writer of The Essential 55, a book about teaching students the rules for life. He helped many students to be better in their lives.
Clark's story started at his school in the US. When he walked into his fifth-grade class, he met lots of problems. The children weren't interested in learning and they often played or slept in class. To help them, Clark wrote down 55 rules for them. Soon the students became better in both study and life. They learnt to be friendly to others and to be the best of themselves.

Clark doesn't think it's hard to teach his students these rules. “I explain(解释) the rules one by one, and then we role-play to show how they work. The first week we just practise. I will tell them when they break(违反) a rule. After that, they should remember and follow the rules strictly.” Clark hopes when his students leave his classroom, these rules will help them to live better.
