Are you looking for examples or for classes to take? I'll go the other route and give some resources you might be able to use if you're wanting to teach an online class. The first one is the obvious Khan Academy - they provide TONS of videos, as well a space to practice: http://www.khanacademy.org/.
I don't have access to the courses themselves, but the community college I used to work for offers math online and they Hawkes Learning Systems to supplement/ for homework: http://www.hawkeslearning.com/.
When I taught math online for them, I used MyMathLab: http://www.mymathlab.com/. It has its own set of advantages and disadvantages. I only taught sub-100, but MyMathLab could be used for any level.
The only math class(es) I have taken online were through Portland Community College in Oregon. I liked the text and instructor. I looked on their website for his website, but didn't find it. Here's the text he used: http://www.amazon.com/Introduction-Practice-Statistics-w-CD/dp/1429216212/ref=sr_1_14?ie=UTF8&qid=1368309133&sr=8-14&keywords=introduction+to+statistics. There are probably less expensive books out there or you can probably find electronic resources that are cheaper.
The college I currently work for is trying to put together a math lab w/ an online component. I am always looking around for resources to that end. I'm happy to share good things as I find them and I try to do that on twitter: http://www.twitter.com/sbethm . That's a good place to contact me, too, if you'd like.
FINALLY, in my snooping I noticed this website for a calculus class at Oregon State University. It looks like it's a supplement for their online class based in BlackBoard: http://oregonstate.edu/instruct/mth251/cq/. In using LMS's, sometimes it's difficult to get a look at online classes - it's nice when they make some of their resources/ materials available to the public.
