Helping Verbs May Might Must Practice Activities
Grade 4 students practise using may, might, and must to show permission, possibility, and necessity in clear, complete sentences.
Practice that builds confidence
Understanding may, might, and must
These Grade 4 grammar worksheets help children understand how the helping verbs may, might, and must change the meaning of a sentence. Students practise choosing the correct modal verb to show permission, possibility, or necessity.
The printable activities include sentence completion, identifying helping verbs, rewriting sentences, and using context clues to decide which word fits best. Each task supports stronger grammar, clearer writing, and more precise word choice.
In Grade 4 writing, students begin to notice that helping verbs do more than support the main verb. May often shows permission or a possible action: “You may begin.” Might suggests a weaker possibility: “It might rain.” Must shows necessity, duty, or a strong conclusion: “You must wear a helmet.” These worksheets focus on how each word changes the meaning of the whole sentence.
Building meaning through context
Children practise reading the full sentence before choosing a helping verb. A sentence about rules, safety, or requirements usually points to must. A sentence asking or giving permission often needs may. A sentence about something uncertain often uses might. Activities may ask students to complete sentences, circle the helping verb, match meanings, or rewrite a sentence so the idea becomes stronger or less certain.
A simple parent routine
At home, read one sentence aloud and ask, “Is this about permission, possibility, or necessity?” Have your child hold up one finger for may, two for might, and three for must before writing the answer. Then ask them to explain the clue words. For example, “rules,” “need to,” or “required” can signal must, while “maybe” or “not sure” can signal might.
Classroom uses for teachers
Teachers can use these printables during a verbs lesson, small-group grammar review, morning work, or literacy centers. They also work well before a writing task: students can revise a paragraph by adding modal helping verbs to show how certain, polite, or necessary an action is. Partners can compare answers and explain why one modal fits better than another.
Common errors to watch for
Some students use may and might as if they mean exactly the same thing. Encourage them to hear the difference between polite permission and uncertain possibility. Others overuse must in sentences that only suggest a chance. Also watch for missing main verbs; in “She must finish,” must helps the main verb finish.

Why iBloom worksheets help

Helpful answers
Frequently asked questions
What do may, might, and must teach Grade 4 students?
They teach students how helping verbs can show different meanings: may can show permission or possibility, might shows uncertainty, and must shows necessity or obligation.
How can my child decide between may and might?
Ask whether the sentence is giving permission or only showing that something is possible. “You may go” gives permission, while “It might snow” shows an uncertain possibility.
Why is must different from may and might?
Must is stronger. It usually shows that something is required, necessary, or very likely based on evidence, such as “You must stop at the red light.”
