His YouTube channel has over 700 lectures and you leave understanding everything he talks about no matter the subject.

Smart Shorties is a new CD being marketed to teachers that takes the beats from popular rap songs and rewrites them to the multiplication tables, with the intent of improving kids' math skills. Forbes has a nice roundup on it's history, and NPR has done a featurette on it as well At the very least, it's certainly worth a listen for the chuckle potential, but in addition to that, it's an interesting example of the now-booming Edutainment industry, something that not only spans CD's, but also computer games and even standalone video game consoles.

also, Smart Shorties is certainly not the only "Hip-hop in the classroom" product out there, nor is it the first.
