ESL warm up activities are a great way to start any English class. It is a win-win for both teachers and students. Teachers can tune themselves in for the upcoming class and buy themselves some time. Students, especially younger ones, can have fun, get to know each other, and learn something new at the same time. Just like athletes need to warm up their muscles before their activities, students need to “warm up” their brains.

In this article we have gathered some engaging, informative, and fun warm up games for ESL students as well as the warm up exercises for kids learning languages.
