"Montessori referred to such specific responses of the adult as "points of interest". It is points of interest that draw children deeper into an activity once engaged, or back to it after they have lost their concentration: the last drop of water from the pitcher while pouring, the tiny pieces of cheese left on the chopper, the spot of flour on the rolling pin, or the flower stem that just reaches the water in the vase. Points of interest, then , help the child to clarify the challenge in an activity. Seeing the challenge in an activity is the motivator to carrying it through to completion and repeating it."
