She taught fifth grade for more than twenty of those years. She taught difficult math formulas with chants and cheers. There was a lot of clapping with the formulas for area of a square, circle, and triangle -- to name a few. As she drilled these formulas, she would say "Keep clappin'!" until the next one she wanted to have the kids to recite came to her mind. Any type of information that needed to be remembered was taught with movement (marches, for example), sound (made up songs or songs from educational internet), and writing (usually explanations).
