While paying attention to (grammar) lessons in English class is important, it's only the first step in mastering how the language works. Playing with language helps you actually use it, and playing word games is more fun than sitting and listening to a lecture. It may sound strange, but playing online games or using printable language games may be more important than what you learn just listening in class. Why? Well, think of language learning as a sport. When you play basketball, you have to know how the ball moves, know how to run, and understand how to throw the ball into the hoop. You learn these skills by practicing them. Even if you become a professional basketball player, you probably started learning to play with friends and family in your driveway or school gym. By the time you join a school team, you might not have to think about how to run or bounce the ball because you've already learned through playing at home. Language follows the same basic rules. Play can be a tool for learning!
