Montessori teachers follow the child's own sense of what they are ready to learn. In their primary role as observers of the child's progress they present materials when the child is ready to take on new work. We see children sensually experiencing various materials and obviously enjoying themselves. Through this freedom, the child becomes more comfortable, taking the time to contemplate all aspects of an activity - the feel, the visual appearance, the sound of the materials, even the smell. This curiousity to explore the sensual world around them is part of what makes learning fun.
