GLM is a year-round Montessori program that offers themed summer sessions (for toddler and preschool students only) with special summer activities within the Montessori program. The summer program provides continuity for returning students, as well as developing teacher/child/family relationships with new students.

An outcome of a Montessori education is a very deep respect for the planet earth and the connections we have to all living things. In this spirit, our summer themes are a study of the various biomes, the communities of plants and animals that have common characteristics for the environment they exist in: Oceans, Forests, Mountains and Deserts. In each session we will study the geography, botany and biology of each of these particular biomes.
