Everyone wants to be happy. A positive attitude can do wonders for your health and self-esteem. It can also help you learn new things. As teachers the world over have seen from first-hand experience, students often learn best when they enjoy their classes. Research also shows this to be true; the book “Positive Psychology in Second-Language Acquisition,” edited by Richard Lake and Zoltán Dörnyei, makes it clear that positive emotions enhance both the teaching and learning of a second language.
Why Teach Happy Idioms?
Teaching students to express their joy in a second language makes it possible for them to share their happy feelings with others. However, it’s not enough for English language learners to express happiness in literal terms such as “I feel happy”. Native English speakers use idioms all the time, and those who want to become fluent in English as a second language need to understand at least some of the idioms that express joy, pleasure, and happiness.

1 ➜ Introduce the idiom and an upbeat expression like “walking on air.”
2 ➜ Have pairs act out a short role-play that shows the positive emotions behind each phrase.
3 ➜ Finish with a reflection slip: “Which happiness idiom best matched your feeling and why?”
This quick routine anchors vocabulary in real experiences and keeps the class energy high.
