Lesson: Modal Verbs
Year: 5 | Subject: English | Time Allocation: 100%
Class/Set: ____________ Date/Term: ____________
LO (WALT): To use modal verbs to indicate degrees of possibility and certainty.
Success Criteria (WILF):
- I can identify modal verbs within a range of sentences.
- I can rank modal verbs on a 'Certainty Scale' from 0% to 100%.
- I can select appropriate modal verbs to change the meaning and tone of my writing.
1. Starter (15%)
- Activity: The 'Certainty Sort' Retrieval Practice.
- Explain: Inform the class that verbs usually tell us an action is happening, but some verbs tell us how sure we are about that action. These are called modal verbs.
- Display: Show the following list of words on the whiteboard: might, must, will, could, should, may, won't, can, shall.
- Challenge: Ask students to draw a horizontal line in their exercise books. On the left, write '0% (Impossible)' and on the right, write '100% (Certain)'.
- Distribute: Students must place at least five of the words from the board onto their scale based on how much certainty they express.
- Discuss: Ask pupils to compare their scales with a partner. Does 'should' feel more certain than 'could'? Why?
2. Main Activity (70%)
Teacher Input:
- Explain: Modal verbs are 'helper' verbs. They sit next to the main verb to change the 'mood' of the sentence. They tell the reader if something is a definite fact, a possibility, or a requirement.
- Model: Write the sentence "It will rain today" on the board. Underneath it, write "It might rain today."
- Script: "Class, look at these two sentences. In the first, I am 100% certain I need my umbrella. In the second, I am only suggesting a possibility. The word 'will' creates a sense of certainty, whereas 'might' suggests a low degree of probability. By changing just one word, I have changed the entire meaning of the message."
- Demonstrate: Introduce the 'Degrees of Certainty' table. Use the table below to show how we categorise these verbs.
| High Certainty (90-100%) |
Medium Probability (50-80%) |
Low Possibility (10-40%) |
| Will / Must / Shall |
Should / Ought to |
Might / Could / May |
- Check: Ask students to examine this sentence: "You should wash your hands." Ask: "Is this a command or a suggestion? How would it change if I used must?"
Student Task:
Direct: Students will complete three progressive tasks to consolidate their understanding of modal verbs in context.
Task A (Identification): Circle the modal verb in each of the following sentences:
- We shall go to the ball later this evening.
- The explorer could see the mountain peak through the mist.
- You must finish your vegetables before having pudding.
- It might be a long journey, so bring a book.
- They should arrive by three o'clock if the traffic is light.
Task B (Application): Rewrite the following 'Certainty' sentences to make them 'Possibility' sentences by changing the modal verb.
- Sentence: "It will snow tomorrow morning." (Change to low possibility).
- Sentence: "You must attend the meeting." (Change to a suggestion).
- Sentence: "I shall win the race." (Change to a slight chance).
Task C (Reasoning & Composition): Look at the 'Crime Scene' prompt below.
- Prompt: A biscuit has been stolen from the staff room. There are three suspects: Mr Smith (seen near the door), Mrs Jones (who likes biscuits), and the Headteacher (who was in a meeting).
- Write: Write three sentences using different modal verbs to explain who you think the thief is. You must use one high certainty verb, one medium probability verb, and one low possibility verb.
- Example: "It could be Mrs Jones because she was hungry."
3. Plenary (15%)
- Check: Facilitate a 'Hinge Question' check. Ask students to show a finger (1, 2, or 3) for the correct answer.
- Question: Which modal verb shows the highest degree of certainty?
- a) ☐ Could
- b) ☐ Might
- c) ☐ Will
- Consolidate: Invite a student to explain why a doctor might use the word 'may' instead of 'will' when talking to a patient. This links the grammar to real-world social nuances (British values of mutual respect and professional accuracy).
4. Resources
- Whiteboard and pens.
- Exercise books and pens.
- Printed 'Degrees of Certainty' table (optional for SEN support).
- Highlighters for Task A.
⚠ TEACHER’S GUIDANCE
💡 Pedagogical Insights
- Year 5 Calibration: At this stage, students are moving from identifying word classes to understanding the effect of word choices on the reader. Ensure you emphasize that modal verbs allow a writer to be subtle or authoritative.
- Common Misconception: Students often confuse modal verbs with adverbs of probability (e.g., 'perhaps', 'maybe'). Remind them that modal verbs almost always appear directly before the main verb (e.g., "must eat", "could go").
- EAL/SEND Support: For students struggling with the abstract concept of 'probability', use a physical 'Probability Line' on the floor. Have them physically stand on the line to represent different words.
🔑 Answer Key
Task A Answer (Identification):
- shall
- could
- must
- might
- should
Task B Answer (Application):
(Note: These are suggested answers; any modal verb from the 'Low' or 'Medium' categories is acceptable as long as it reduces certainty).
- It might/could/may snow tomorrow morning.
- You should/ought to attend the meeting.
- I might/could/may win the race.
Task C Answer (Composition):
- High Certainty: "Mr Smith must be the thief because his crumbs were found."
- Medium Probability: "Mrs Jones should be questioned because she loves ginger nuts."
- Low Possibility: "The Headteacher might have taken it, but he was in a meeting."
Plenary Answer:
- Correct Answer: c) ☐ Will. ('Will' expresses a definite future action, whereas 'could' and 'might' express possibility).
