I replied to Shawn,
Dancing in a math lesson will not improve thinking. THINKING advances mathematical thinking.”
A cute “engaging” math song might energize the kids but it won’t make them better at math. Surely, “memory is the residue of thought” and it is actually the main key to thinking (see D.T. Willingham’s posts on cognition and learning), but to use dance in 2nd grade as a way to memorize subtraction facts is not the most effective way. Despite the general belief that testing is damaging, cognitive science demonstrated that testing has a far greater impact than additional study. So if you want kids to memorize their number facts (so as to give space to higher-order thinking in solving problems) instead of making them dance it is better to allow them to self-test or to test each other in pairs.
