For the first time, Basic Montessori opens the celebrated philosophy and method to a more general public. David Gettman has devised a clear and modern explanation of Montessori's revolutionary ideas about early intellectual development, and provides a step-by-step guide to the Montessori learning activities most commonly used with under-fives. These include activities for introducing reading and writing, counting and decimal concepts, science, and geography, as well as activities that help develop the child's practical and sensorial skills.
