The chalkboards being removed to make way for new whiteboards are in four classrooms, according to the Oklahoma City Public School District.
A spokeswoman said the district is working with the city to “preserve the ‘chalk’ work of the teachers that has been captured in time.”
A wheel that apparently was used to teach multiplication tables appears on one board. “I have never seen that technique in my life,” Kishore told the Oklahoman.
The boards carry not just teachers’ work, but also that of students, and every room has a lesson on pilgrims, according to the district.
“Their names are here; I don’t know whether they were students in charge that day that got to do the special chores if they were the ones that had a little extra to do because they were acting up,” Kishore said. “But it’s all kinds of different feelings when you look at this.”
