Green Elm School was a one-room schoolhouse built in the 1870's in southeast Kansas, in the southwest corner of Crawford County, seven miles north and one mile west of McCune, Kansas. It held classes from 1872 to 1955 and employed sixty-six different teachers. Its name came from an elm tree near the school, and the building also served as a church until October 1910. The United Chapel Church organization first began meeting and holding worship services there in 1883, one mile north of the present church. Many teachers were only a year or two older than their students, and their first contracts lasted only three months, during which they boarded in area homes. One teacher was responsible for all students from first grade through eighth grade. The school was heated by a large coal stove, and the teacher and larger boys hauled coal from the coal shed south of the school. The teacher also carried a bucket of water from a nearby well into the schoolhouse, and everyone drank from it with a cup or dipper. Nearly all students walked to school on dirt roads, since none were paved or covered with crushed rock. Students had two recesses and a noon play time, and a big slide and swings stood next to the school, along with separate outhouses for boys and girls. The building was moved to the George E. Nettles Elementary School playground in Pittsburg in 1976, and then moved to the museum property in March 1981, where visitors have enjoyed it for several decades.
