Old-School Teacher Makes Magic Blackboard Graph

These math students are used to using computers and projectors in class, but you can always teach young dogs old tricks. When the class got a substitute teacher for the day they were brought back to the ‘old school’. The student behind the camera, Tash-had Sadiq, recounted that the elderly teacher had brought what “looked like wallpaper” with her, held it against the board and rubbed it with the chalk eraser. Voila! A graph is born.

Tash-had went on to say that the class “were amazed” as they had “never seen anything like it before.” The teacher, however, appeared unimpressed with the ecstatic reaction to her neat trick. Credit: YouTube/tashad200
