I'm never sure what I should think when I read stories about singing/rapping math teachers. First of all, does the story give an accurate view of that teacher's classroom? Surely it's not all singing, all the time. Do stories like this unfairly distort the public's idea of what represents a good math teacher? Can music really take students to a level of understanding beyond memorization? (See the slope music video and decide for yourself: http://www.youtube.com/watch?v=JD5X1Z1IhsQ.)
