Integrating language skills in your lesson can kill two birds with one stone: you can cover more material and attempt to simulate a more natural language environment (in my humble opinion).
There are many ways to do this, but one quick way is by using listening to introduce key language (like vocabulary or grammar). Pick a conversation or a song (If you can’t find one, just record one yourself! You can do this easily with this website.) that includes the language point you are covering. Prepare some questions for the students answer while listening to help them highlight key points of the language being taught. By answering the questions about the language, they are encountering the grammar or vocabulary you want to teach while at the same time getting some listening practice in.
This method can also help speed up the clarification of the lesson’s language because your students will already have answered most of their own questions through the language analysis provided while listening. In the end, this can give them more time to focus on practicing in class :). So, try it out if you haven’t already!
