grammar - Is it okay to use お願いします when asking your teacher for help?

When asking a teacher for help, is it okay to use お願いします?

For example, asking to check my homework:

宿題をチェックしてお願いします。

To me, "Please check my homework." sounds kind of rude.

Would saying

宿題をチェックしてお願いできますか? (Would it be possible for you to check my homework?)

be any better ?
