Modal VerbsYear 5 Lesson Plan

National Curriculum: English Appendix 2 — Grammar: modal verbs or adverbs to indicate degrees of possibility (Year 5)

Overview

Pupils learn to identify and use modal verbs to indicate degrees of possibility, certainty, and obligation. They explore how changing the modal verb shifts the meaning of a sentence, and practise using modals effectively in persuasive and formal writing contexts.

Learning Objectives

  • Identify modal verbs in sentences and explain their function.
  • Understand that modals indicate degrees of possibility or obligation.
  • Select appropriate modal verbs for different levels of certainty.
  • Use modal verbs effectively in persuasive and formal writing.

Key Vocabulary

modal verb
A type of auxiliary verb that expresses possibility, permission, ability, or obligation, e.g. 'can', 'could', 'will', 'would', 'may', 'might', 'shall', 'should', 'must'.
possibility
The chance that something might happen.
certainty
Being sure that something is true or will happen.
obligation
Something you must or should do.
auxiliary verb
A helper verb that supports the main verb in a sentence.
degree
The level or amount of something, e.g. how certain or likely something is.

Suggested Lesson Structure

10m
Starter

Write on the board: 'You ___ do your homework.' Fill the gap with: must / should / could / might. Ask: how does each one change the meaning? Discuss the differences in tone and obligation.

20m
Teaching input

Introduce the modal verb family. Create a certainty scale: might → could → should → will → must (increasing certainty/obligation). Explore modals in different contexts: scientific writing ('the ice may melt'), persuasive writing ('you should act now'), instructions ('you must wear PPE').

15m
Guided practice

Pupils rewrite a set of sentences using different modal verbs and discuss how the meaning changes. Sort modals onto a certainty/obligation scale.

10m
Independent practice

Pupils write a short persuasive paragraph about a topic of their choice, deliberately using at least three different modal verbs to vary the degree of certainty and obligation.

5m
Plenary

Share examples. Discuss: which modals were most effective for persuasion? Recap the certainty scale and key modals.

Common Misconceptions

  • Pupils sometimes confuse 'can' (ability) with 'may' (permission) — both are modals but serve different functions.
  • Using 'must of' or 'should of' instead of 'must have' / 'should have' — a common spoken-language error to address explicitly.

Prior Knowledge

Pupils should already be able to:

  • Knowledge of verbs and auxiliary verbs.
  • Familiarity with expressing certainty and possibility in speech.
  • Some experience with formal writing contexts.
