An observer of our Upper Elementary classroom would see most of the children collaborating on their work; this is intentional. Montessori elementary communities are designed to support this collaboration because it is recognized as a need for this age group. Elementary children crave interaction, not just in a purely social setting, but also in organized groups where they are focused on a goal with their peers. At this age, children form strong attachments to friends and want to be surrounded by their peers. For this reason, most of their work is collaborative, with the exception of when they are working on individualized skills. This is also the phase for “acquisition of culture” (Montessori). This is one reason why there is such a strong focus on learning about how people throughout history have contributed to society. The children assimilate this new knowledge about history as they are learning to contribute to their own world, classroom and beyond.
This week our fourth grade geometry work focused on proving the equivalence of a triangle and rectangle. This work starts sensorially; the children use a metal inset material to prove the equivalence of the two shapes. After using the material, we discuss the requirements for the equivalence of a triangle and rectangle; when the base of the two shapes is equal and the height of the rectangle is half that of the triangle. The fifth graders focused on inverse area formulas. They learned how to find the height when given the base and area, and how to find the base when given the height and area. In biology we continued our lessons on the circulation of plants with a discussion and demonstration about capillarity; the upward movement of liquids as a result of surface tension. In history this week, the fourth years learned about the Mesozoic Era of the Timeline of Life (250 to 65 million years ago) and the fifth years learned about the Magdalenian people (17,000 to 12,000 years ago), the last group of modern humans in the Upper Paleolithic Age. The children’s enthusiasm about our Literature Circles continues to grow. They are enjoying discussing their books and sharing their roles with the group.
