I've found Sage a great complement to my abstract algebra course. Based on last fall's course (2008) I created a primer of Sage commands useful for learning group theory.
http://abstract.ups.edu/sage-aata.html I'll likely update it after this fall's course ends and then expand it this spring when I teach rings, fields, etc. I'll greatly expand my use of Sage in my linear algebra course which I will teach again this spring after a bit of a break. I've also found Sage's 3D plots extremely useful for teaching multivariate calculus. One important feature to realize about Sage is that it can often represent mathematical objects exactly. For example, the null space (kernel) of a matrix is a *vector space*, not just a pile of basis vectors. Then you can do many of the things you might do with a vector space, like asking for its dimension, or intersecting it with another vector space. I find this a valuable feature when using Sage with students.
