Hello Headmaster,
There are three students I've been assigned to watch (Cases 1, 2, and 3). I believe they will be ready in a couple months' time.
Sincerely,
Student #1021

Dear #1021 (you must tell me your name later!),
I'd like to assign you to a fourth. She doesn't live far from the three you are currently in charge of, and she will be also ready in a couple months' time.
From,
Your Headmaster
