Maria Montessori observed that there are certain times in a child’s life when it is very easy to learn a skill. Her observations are now substantiated by modern brain research, and are commonly referred to as critical periods.

As an example, when a child is in the sensitive period for language he can learn to speak and understand easily, with no formal instruction. Don’t we all wish we had learned a second language as a young child?

Montessori teachers are trained to carefully observe for signs of sensitive periods, and then answer by presenting work that will meet the needs of the sensitive period.
