Ten Idioms for Children


Learning idioms can be fun for young English students as it is like learning a secret language. Usually, an idiom is a group of words or a phrase that has a different meaning to the words themselves. For example, “a piece of cake” is nothing to do with food. You say it if you think something is easy. Don’t ask me why. That is the fun of idioms. They often don’t make any sense. The following are some idioms that students can try and use in everyday life. Either at home or school.

1. A piece of cake

If something is very easy, you say that it is a “piece of cake”.

Teacher: How was your math exam this morning?
Student: It was a piece of cake!

2. Play it by ear

If you are not sure how to do something or you don’t have a plan yet, you say that you will “play it by ear”.

Mother: What will you do after football practice?
John: I am not sure. I will play it by ear.

3. Cat got your tongue?

If someone is quiet and not talking, you say “has the cat got your tongue?”

Suda: Why aren’t you talking? Has the cat got your tongue?”

4. Raining cats and dogs

If it is raining really hard, you say, “it is raining cats and dogs”.

5. A penny for your thoughts

If your friend is sitting quietly and it looks like he is thinking about something, you say “a penny for your thoughts”.
