A little help from one's friends
Children in Montessori classrooms often spontaneously help one another, just as the late Montessori biographer E.M. Standing affectionately describes witnessing here:
“Only last week, as I was observing in a Montessori class of forty (where the average age was under five), I watched a little boy of three and a half pouring rice from a jug into a cup. As he did so he spilt some of the grains on to the floor. Suddenly, as from nowhere, prompt as the fire brigade, a little girl of four and a half arrived on the scene with a miniature broom and began sweeping the fallen grains together. She had scarcely finished doing this when another child, even younger, appeared and gathered them into a tiny dustpan. Everything happened quite spontaneously. The teacher, who was at the other end of the room with her back turned, did not even know what was taking place.”
