Two Upper Elementary students had an A-ha Montessori moment yesterday that I would like to share…. They had been doing the decanomial work which introduces squaring and cubing and is a precursor to multiples and factors. The students began by laying out beads from the bead bar box (1 one-bar taken once is one, 1 one-bar taken twice is two, etc, then 1 two-bar taken once is two, 1 two-bar taken twice is four, etc, etc, up to doing this with ten-bars). Doing this they were able to identify when a number was squared because the bead bars literally formed a square.
