The AP Statistics community is very giving. This page has links to several very nice pages / sites to see just how much material is out there. I have to admit, I steal from these people often to use in class.

I NEVER post their material without permission and citations though.

My Twitter PLC includes the following teachers:

Mr. C and his class wiki

Other AP teachers around the web

The AP Statistics FAQ for new teachers is also a great place to start finding resoruces. It is compiled and hosted by Mr. Derkson.

Hatboro-Horsham AP Stats is a very straightforward site that contains notes, test reviews, etc.
Viva Hathaway's AP Stats I had the priviledge of attending one of Viva's sessions at an NCTM conference. She is terrific. She creates tons of materials for her learners, and shares them with teachers over the world. I have some of her materials on this site, and I use them in class. More recently, however, her school's site is behind a password firewall.

Herkhimers Hideaway is the website of Sanderson Smith. He is retired from teaching but he still has materials for use on his site.
Mr. Tabor's AP Stats this is his TeacherWeb site for AP stats. It looks like (in 2011) that he is not adding much to it any more, although he does have some applets created and hosted here.

Mr. Roger's AP Stats has a very good site with lots of resources for his learners here.

Mr. Hanson's AP Stats the STAtistics Zone (as he calls it) hasn't been updated since 2009, but there are resources here as well.

Mr. Lieb's AP Stats has calculator (TI-83) programs written to help learn and do statitics, as well as some resources. Although I have had problems accessing things on the site.

Mrs. Krummel has free and paid resources available for AP Stats teachers. I like some of the things she has. Not sure if I would buy any yet though.
Mrs. Temple wipes her site every year and rebuilds it as the year goes on. It is useful to see what another teacher is doing and if you are current with someone else.
Mrs. Smith organizes everything on a calendar, which is nice to help newer teachers see with other teachers are doing and the order she is doing it in.
Exeter Acadamy has some resources available for AP Statistics as well as resources for all other math classes.
