8. Classroom chalkboards
Want to make your kids think you’re really old — like “rode-dinosaurs-to-school” old? Tell them about your school days spent clapping erasers to get the chalk dust out of them. That’s a chore today’s students may never understand.
Chalkboards, aka blackboards, have long been on the way out, replaced by their cleaner, smoother cousin, the whiteboard. Popularized in the 1990s, whiteboards can be written on with special markers, often in bright colors, that are easy to wipe off.
But even traditional whiteboards are likely to be replaced with emerging smartboards — a high-tech, interactive version — as the price of the new technology comes down.
