Note for teachers using this lesson plan
This lesson focuses on helping students understand the meaning of idiomatic expressions in English. Teachers should prepare by having dictionaries (physical or online) readily available and be ready to guide group work effectively. The central concept is that idioms have meanings not directly derivable from their individual words. By the end of the lesson, learners should be able to define idioms and correctly state the meanings of various idiomatic expressions.

Lesson Content/Board Summary
Idiomatic Expressions
Meaning of Idiomatic Expressions
An idiomatic expression, or idiom, is a phrase or expression whose meaning cannot be understood from the ordinary meaning of its individual words. The meaning of an idiom is often figurative and has to be learned as a whole unit. Idioms add colour, vividness, and expressiveness to language, but they can be confusing if their non-literal meanings are not known.
Examples of Idiomatic Expressions and Their Meanings
Here are some common idiomatic expressions and their meanings:
- Break a leg – This means “good luck.” It is often said to performers before a show.
- Bite the bullet – This means to endure a difficult or unpleasant situation.
- Hit the road – This means to leave or depart.
- It’s raining cats and dogs – This means it is raining very heavily.
- Let the cat out of the bag – This means to accidentally reveal a secret.
- Once in a blue moon – This means very rarely.
- Piece of cake – This means something that is very easy to do.
- Spill the beans – This means to reveal a secret.
- Under the weather – This means feeling unwell or sick.
- When pigs fly – This means something that will never happen.
- Cost an arm and a leg – This means something is very expensive.
- Get cold feet – This means to become nervous or lose courage before doing something.
- Keep an eye on – This means to watch or look after something or someone.
- Turn a blind eye – This means to ignore something wrong or unpleasant.
- A blessing in disguise – This means something that seems bad at first but turns out to be good.

Instructional Procedures
Step 1: Introduction
Time: 5 minutes
Teaching Skill: Engaging/Activating Prior Knowledge
Teacher’s Activity: The teacher greets the students and asks them if they have ever heard phrases like “It’s raining cats and dogs” or “Break a leg” and what they think these phrases mean literally. The teacher then introduces the topic of idiomatic expressions.
Pupils’ Activity: Pupils respond to the teacher’s questions and share their initial thoughts on the phrases.
Learning Point: Introduction to idioms
Step 2: Explanation of Idiomatic Expressions
Time: 10 minutes
Teaching Skill: Explanation/Definition
Teacher’s Activity: The teacher defines idiomatic expressions, explaining that their meanings cannot be understood from the literal meanings of the individual words. The teacher provides a few simple examples and explains their true meanings.
Pupils’ Activity: Pupils listen attentively, ask questions for clarity, and try to guess the meanings of the examples given.
Learning Point: Meaning of idioms
Step 3: Group Activity – Identifying Idioms
Time: 10 minutes
Teaching Skill: Group Facilitation/Observation
Teacher’s Activity: The teacher divides the students into small groups and provides each group with a list of sentences containing various idiomatic expressions (without their meanings). The teacher instructs them to identify the idiomatic expressions in each sentence.
Pupils’ Activity: Pupils work in their groups to identify the idiomatic expressions from the provided sentences.
Learning Point: Identifying idiomatic phrases
Step 4: Group Activity – Looking up Meanings
Time: 10 minutes
Teaching Skill: Guided Practice/Resource Utilisation
Teacher’s Activity: The teacher instructs the groups to use dictionaries (physical or online) to look up the meanings of the idiomatic expressions they identified in the previous step. The teacher moves around to assist and guide the groups.
Pupils’ Activity: Pupils actively use dictionaries to find the meanings of the idiomatic expressions, discussing their findings within their groups.
Learning Point: Using dictionaries for idioms
Step 5: Class Discussion and Sharing
Time: 10 minutes
Teaching Skill: Facilitation/Feedback
Teacher’s Activity: The teacher calls upon each group to share one or two idiomatic expressions they found and their corresponding meanings. The teacher provides feedback and clarifies any misconceptions.
Pupils’ Activity: Groups present their findings to the class, and other pupils listen and compare with their own findings.
Learning Point: Shared idiom meanings
Step 6: Reinforcement and Examples
Time: 5 minutes
Teaching Skill: Reinforcement/Elaboration
Teacher’s Activity: The teacher reinforces the concept of idioms by providing additional examples not covered by the groups, explaining their meanings, and briefly showing how they can be used in sentences.
Pupils’ Activity: Pupils listen and make mental notes of the new examples and their meanings.
Learning Point: Further idiom understanding
Step 7: Evaluation/Review
Time: 5 minutes
Teaching Skill: Questioning/Assessment
Teacher’s Activity: The teacher evaluates the learning by asking the following questions:
- What is an idiomatic expression?
- What does “break a leg” mean?
- If someone is “under the weather,” what does that imply?
- Explain the meaning of “let the cat out of the bag.”
Pupils’ Activity: Pupils answer orally and in writing.
Learning Point: Understanding idiom meanings
Step 8: Note-Taking
Time: 10 minutes
Teaching Skill: Guided Writing
Teacher’s Activity: The teacher guides pupils/students to copy the essential Board Summary notes, including the definition and examples of idiomatic expressions and their meanings, into their notebooks.
Pupils’ Activity: Pupils/students copy the notes carefully into their notebooks.
Learning Point: Recording lesson notes
Step 9: Conclusion
Time: 5 minutes
Teaching Skill: Summarisation
Teacher’s Activity: The teacher briefly summarises the lesson by reminding students that idioms are an important part of English and encourage them to pay attention to and learn more idiomatic expressions they encounter.
Pupils’ Activity: Pupils listen to the summary and prepare for the next lesson.
Learning Point: Consolidation of idiom concept
Continuous Assessment/Further Study
Type: Homework
Instruction: Research and write down five more idiomatic expressions that were not discussed in class. For each idiom, write its meaning and use it correctly in a sentence.
- Idiom 1: Meaning and Sentence
- Idiom 2: Meaning and Sentence
- Idiom 3: Meaning and Sentence
- Idiom 4: Meaning and Sentence
- Idiom 5: Meaning and Sentence
Lesson Keywords
- Idiom – A group of words established by usage as having a meaning not deducible from those of the individual words.
- Expression – A word or phrase.
- Figurative language – Language that uses words or expressions with a meaning that is different from the literal interpretation.
