Lesson Plan July 10, 2026
Topic: Modal Verbs (2)
In this lesson we will learn about using modal verbs to talk about possibility and probability using could, might, may and willprobably.
Section A: May and Might
You use may and might to talk about something which is possible, but we are not sure about.
In the present
A: Have you seen David?
B: He might be in his room.
A: No, he isn’t. I’ve looked.
B: Well, he may be at the shopping mall then.
In the future
A: Have you got any plans for this evening?
B: I might go to the movies. Do you want to come?
A: No thanks. I may just stay home and have dinner.
The meaning of may and might in these sentences is the same.
Remember!
For negatives, you add not or n’t to might (might not or mightn’t)
For may, you only add not (may not)
Section B: Could and Will Probably
You can use could to talk about something you are not sure about in the present or future.
Be quiet, please. The baby could be asleep.
It could be too hot to go to the beach tomorrow.
Could we save enough money to got on holiday next spring?
You use will probably when you are more sure about something.
I’ve missed the last bus. I could get a taxi but I’ll probably just walk home instead.
Lesson Notes
Words & Phrases

Modal Verbs (2)
This weather could last all week. (= continue all week)
"I bought enough groceries to last all week." (= I have enough food to continue eating until next week).
Will your Apple Watch’s battery last all week on a single charge?”
Speaker A: "What are your plans for the summer vacation?"
Speaker B: "We haven't booked anything, but we MIGHT travel to Greece."a. might (correct: used for lower to medium chances)
b. will probably (incorrect: used for high chances)
"It ain't gonna rain this afternoon” is grammatically incorrect in standard, formal English. However, you will hear it constantly in movies, casual conversations, and pop music.
"Ain't" is slang for is not / am not / are not / have not / has not
"Gonna" is a casual contraction of going to.
If a native speaker says, "It ain't gonna rain this afternoon," they are being highly informal and usually mean they are 100% sure it won't rain. ("Ain't" can replace FIVE different verbs, and works even if the subject is singular or plural!)
"Don't look at me, it ain't my fault.” (is not)
I ain't going out in this heat—it's like an oven out there! (am not)
"We ain't ready to leave yet, give us five more minutes.” (are not)
"They ain't got any cash on them right now, sorry.” (don’t have)
“My air conditioner ain’t been working right.” (has not)
