Hip-hop mathematics

The math conference on October 17,2008 in Eatonton, Georgia was great! I did not have a chance to see everything but hip hop math was one of many interesting technology that we can use in a mathematics classroom to help students learn. The speaker was from Emory University. He was blessed with musical talent and wrote many hip-hop tunes to teach his students math. The Pythagorean Theorem rap was one of my favorites. Another session I saw was practical mathematical projects where students create a graph of car prices vs. age to learn about regression line, slope, x-and y-intercepts and what they mean. For example, the x-intercept means the car is worthless. If the car lies on the line, it's right on the money. If the data point is above the line, the car is too expensive. If the data point is below the line, buying the car is a very good deal. Lessons or projects like so will probably help students retain the knowledge more than simple formulas of a^2 = b^2 + c^2 or m=(y1-y2)/(x1-x2). Did anyone else attend this session or similar sessions? Please share your ideas of using different technologies and projects that students can relate to in a math classroom.

Would it be cool if we can get this guy to play a song to motivate some mission impossible lesson?
