Research Experience for Undergraduates
REUs are typically eight- to ten-week summer research programs. Every year about two dozen universities across the country run an REU. Participants get first-hand experience of how mathematical research works, get a broader exposure to the world of mathematics than is obtained from course work alone, and usually have a lot of fun!
Here are links to some more information about REUs:

There are also a number of summer schools that have tutorials and workshops aimed towards undergraduates. Here are links to some information:
