This morning we had a fine example of a child choosing to learn rather than play. Paul had been cutting some spindles for a bannister rail. They were on the table waiting to be used when Netti and the children arrived. After a few minutes, whilst the boys were playing in the front room, Lillian began to re-arrange the lengths of wood. After telling Paul that the short piece was a rhombus and a parallelogram she placed it on top of two of the longer pieces. She then balanced the remaining two long pieces on top of the short piece. Then followed an impromptu lesson on centres of gravity, balance points, pivots, rotation, torsion and torque.
