Inspired by the Khan Academy video tutorials for math and science, a 6th grade student, his math teacher, and I formulated a way for him to extend his learning of math concepts. He knows the content forward and backward and we needed to provide some extension activities to keep him engaged. So, we thought he could practice explaining different math problems. This first example is a relatively simple one but it challenged him to break down a problem into chunks that could be easily understood and digested by his fellow students. The student's comment was that teaching the math problem was much more difficult that just doing the problem. Hey, a new respect for the teaching profession! ;-)
