How are you today?
I'm good.
I'm great!
Not bad.
I'm happy.
I'm sleepy.
I'm tired.
I'm hungry.
聞き返すときは → And you? / How about you? / How's it going? / How are things going? / How is everything?
🎯 ONE POINT — Mr. Toshi Do not answer “I'm so so.” → Say “I'm good.”
so so では「どんな感じか」が伝わらず、会話がそこで止まります。
「I'm fine. Thank you. And you?」も今はほとんど使いません。
I'm good./I'm great!/Not bad. で答えて、そのあと聞き返しましょう。

- If you model the sentence, the student must say it again.
Teacher output ≠ Student output
- Check the iPad screens from behind the students, not from the front
- If one student has no partner: seat them near you and use Output Training in the app
"How much English did the students actually use?"
授業のあと、これを自分に聞いてください。
「自分がどれだけ教えたか」ではありません。
