Hi, teachers! At ESL Library, we believe that every day is Earth Day. We hope you'll use the month of April to discuss several topics from our lesson collection on the Environment. You may also be interested in teaching your students about some historic events that took place in the month of April, such as the sinking of the Titanic and the Chernobyl accident. If your students like learning idioms and want to know about holidays around the world, they'll love our Golden Week lesson. Have a fantastic month!
