1.   Fact Monster, www.factmonster.com, part of the Learning Network, is a homework help site that appears aimed at a younger audience.

2.   Homework sites that carry ads say they filter them carefully for age-appropriateness, but some slips are probably inevitable.

3.   I brought textbooks home to complete the assignments but primarily relied on the Internet and the various homework help sites to answer my questions.

4.   The AOL Tutoring Room is what truly sets this Web resource apart from most other homework helper sites.

5.   What I found was that homework sites are frequently trustworthy and accurate and that some provide amazingly speedy responses.
