Lessons so big, they don’t fit in the classroom.

The Lower Elementary hallway is a flurry of activity as Third Years have taken over the space with their Timeline of Life work. Part of the Five Great Lessons of Montessori, the Timeline of Life delves into all plants and animals that have ever lived on our planet—from the tiniest of microorganisms to the largest of reptiles.

It has been fantastic to watch our Third Years working together on the Timeline of Life, discussing eras, periods and epochs and which animals appeared on Earth during which time periods. We have all enjoyed observing their exclamations of excitement and the energy they have for this work. (If your Third Year starts asking for a pet trilobite, you’ll understand why.)

The five Great Lessons are unique and important to the Montessori Elementary curriculum. They are intentionally bold and visual as to inspire the imaginations of the 6‒9-year-old child. The lessons provide a departure from the Lower School curriculum where presentations start small and move gradually to broader conceptual understanding. The Great Lessons start with the biggest idea of all—the Universe—and then move into the smaller ideas that make up pieces of the whole.
