Use of could

1. Introduction to "Could"

Start by explaining:

• "Could" is the past tense of "can" (I could swim when I was a child.)
• It is also used for polite requests, possibilities, and abilities in the past.

Use examples with visuals or gestures:

• I can lift this box (demonstrate lifting).
• Yesterday, I could lift this box, but today I am tired.

2. Interactive Activities

A. Role-Play: Asking for Permission/Requests

Students pair up and practice:

1. One student asks politely using "Could"
   • “Could you help me with my homework?”
   • “Could I borrow your book?”
2. The other responds politely
   • “Sure, I could help.”
   • “I’m sorry, I couldn’t lend it right now.”

B. Guessing Game (Possibility)

• Show different pictures (rainy cloud, crowded train, broken car).
• Ask: "What could happen?"
• Expected answers:
  • "It could rain."
  • "The train could be late."

C. Story Building (Past Ability)

• Start a sentence: "When I was a child, I could..."
• Each student adds something about their past ability.
  • "...ride a bicycle."
  • "...play the piano."
  • "...run very fast."

3. Quick Fun Drills

• True or False: Give statements like “Could you speak English when you were 5?” and let students respond.
• Situational Dialogues: Give a situation: "You are in a restaurant. How do you ask for water politely?" (Answer: "Could I have a glass of water, please?")

4. Wrap-Up and Practice

• Have students recall three uses of "Could".
• Give homework: Write 5 sentences using "could" in different contexts.
