Then, in the 1830s, a German teacher and staunch nature lover named Friedrich Froebel picked up on the idea that play is key to children’s physical, moral, and spiritual development. He was so convinced of this idea that he decided to create an early childhood education program that revolved around singing, dancing, gardening, self-directed play, and experiencing nature with all senses. Froebel viewed children as plants who would flower if they were allowed to learn at their own pace, nourished and guided by a teacher. He called his concept “kindergarten”—literally, a child’s garden.
