How To Teaching English Idioms

Teaching English idioms to English language learners can be incredibly fun. It can also be quite challenging and confusing to students as idioms often don’t make much literal sense. To ensure your English lessons about Idioms are fun and useful to your students, follow these simple tips.

Help Students Understand What Idioms Are

Before students learn some fun English idioms, they must first understand what exactly idioms are. All languages are full of idioms so a great way to introduce the topic of English idioms is to first talk about an idiom in the students’ native language. For example, in Korean, there is an idiom that translates as ‘When Am I going to eat your noodles?’ which means ‘When are you going to get married?’.

Using an example from the students’ native language, you can explain that idioms are expressions in which the meaning cannot be understood by the individual words in that sentence.

Guess The Meaning Of Some Idioms

Once students have an understanding of what idioms are, write a few fun idioms on the board and ask students to guess the meanings of those idioms based on their first impression. This can lead to some very funny guesses and is a great way to make your English idioms class more fun.

Provide Example Sentences

After students have made their initial guesses, write some example sentences with idioms to put them in context. If possible provide some pictures to help students visualize the situations in which these idioms would be used in English conversation.

After providing some examples, ask students again to try and guess the meaning and usage of the idioms and see if their guesses have changed. Then let your students know the true meaning of the English idioms and see if they guessed correctly.


A wonderful way to get students to practice speaking using English idioms is to ask them to come up with a short role play in pairs or small groups. Give each group a particular English idiom and an example sentence/situation to help them understand how to use the idiom.

Ask them to imagine a situation where they can use that idiom and to then create a simple dialogue that they can act out which includes that expression. This fun activity will help students truly understand the meaning and usage of English idioms and will help them to retain the information going forward.
