O-level letter (organizing a party for young school children) - how to start?

As part of your extra-curricular activities, your Principal wants your class to hold a party for young
school children. He asks you to explain in a letter how you would organise the event.

Write your letter. In it you must include the following:

- When and where the party will be held.
- How you will decorate the place.
- How you will provide the refreshments.
- Details of the entertainment.
- How you would like your teachers to be involved.

You must cover all five points in detail. You should add further details if you wish and make your letter
polite but persuasive.

PLease guide me how to start, finish and the pattern! actually my language is not so good! PLEASE

I would be really grateful if you could help me! my boards are coming up really soon!

THANKYOU ^_^

Ok, start with. Dear Sir or Madam,
I am delighted with the possibility of hosting this party and have given much consideration to making it a special and memorable event for everyone attending...(then, as instructed, spend a little time on each of the 5 details, for example) I feel that -------- would be a delightful place to host such an event because of the room, comfort, etc...and elaborate...as far as decorations, naturally, fun bright colors for children...just incorporate a couple sentences or a paragraph for each checkpoint on your list. You could have the teachers be involved by having them each come up with a fun/educational activity table with games, art, etc. Just show lots of enthusiasm (to make it persuasive, as instructed) and be sure to close it with." It would be an honor to help facilitate such a joyous ooccasion and I greatly appreciate your consideration, sincerely _______

I hope this helps!! Good luck
