On Friday, the Oklahoman reported that a set of charming chalkboard lessons frozen in time from 1917 were discovered during renovations of three classrooms at Emerson High School in Oklahoma City.
The school was built in 1895, and the preserved slate blackboards were covered with new chalkboards in late 1917, which we know thanks to the company that installed them and left behind a chalk-written note (see below). Nearly a century later, workers discovered the lessons while installing new whiteboards and smartboards. Once uncovered, the chalkboards revealed a rare and stunning time capsule containing lessons about math, reading, music, handwriting, personal hygiene, pilgrims, and God. Old-timey names such as Agnes, Gladys, Homer, and Mabel were written next to a subtraction problem.*
The Oklahoma City School District is currently figuring out what to do with the remarkably well-preserved 98-year-old chalkboards, which can be seen below.
