Students can't add fractions...and such.

grad students in mathematics

[  Current Mood 
  frustrated  ]  I have been frustrated for some time now about the fact that many of the students that I teach cannot perform the most basic math tasks such as adding fractions, taking roots, and so on without the assistance of a calculator. I teach at UMass, Amherst, and in Massachusetts, they only require two years of math to graduate high school. I imagine some of these problems can be attributed to students forgetting everything they ever learned in their junior and sophomore years. However, this is only a small part of it. Problems with the educational system aside, I was wondering if any of the other TA's out there have any good references for websites, etc, which I could pass along to my students who are having these troubles. I just can't take up time in a college level course (such as precalc) to reteach things like adding fractions and long division. I know there are many sites out there, but I thought if any of you knew of some particularly good ones, it might prove beneficial. Thanks so much for any advice.
