The above mentioned being said, Montessori academics are often hailed as some of the highest standards there are. It is not uncommon to see four-year-olds in our schools reading, six-year-olds completing long division problems, and nine-year-olds classifying botanical specimens. These tasks are completed joyfully, in part because we present information in such a way that children discover it for themselves rather than passively taking in facts given by an adult.
Another reason Montessori students seem to work at an advanced academic level is because of what we call sensitive periods. Through years of observation, Dr. Maria Montessori noticed that young children seemed primed and particularly interested and ready to develop certain skills during very specific time periods. While, of course, there is variation between individual children, she noticed some general patterns that have helped us develop our curriculum. One interesting example is that of the study of geometry. Many of us were first exposed to the subject during our high school years, when it turns out that primary- and elementary-aged children are not only interested in geometry, but have a great capacity to learn far more than we typically give them credit for. This is why you may hear your five-year-old talking about rectangular prisms, or your seven-year-old discussing the differences between isosceles, right, and scalene triangles.
