Walnut Grove One Room School
One-room schools were commonplace throughout rural portions of various countries including the United States, Canada, Australia, New Zealand, United Kingdom and Ireland in the late 19th and early 20th centuries. In most rural (country) and small town schools, all of the students met in a single room. There, a single teacher taught academic basics to five to eight grade levels of elementary-age boys and girls.

In 1990 the school was cut into three pieces and relocated to the Muscatatuck Park.
