Why teachers should not give homework on weekends in two minutes?

WikiAnswers isn't going to write you a two-minute speech because cheating is wrong. It's lying and stealing and we don't do that on our website. We WILL help you learn how to write your own speech.

Make a list of everything you can think of that would be a reason not to give homework on the weekend. Put each item on your list into a proper grammatical sentence and string them into some order. Explain each item on the list with one or two more sentences and you've got a good essay which can be read aloud as a speech. Just pretend you're talking to your friends and give them your reasons.
