"When to teach this lesson on facial expressions? This is a speaking lesson plan that is great to use to introduce facial expressions. Facial expressions are important to study as they provide non-verbal cues and information. They can provide nearly as much information as spoken words do. They can be difficult to understand but when understood students can remain confident when interacting with others in English. This is a great lesson to introduce to upper-intermediate students that have been looking to develop a deeper understanding of English vocabulary in conversational contexts.
