When I came to my school 9 years ago, there was hardly any technology in the classrooms. The overhead projector was the biggest piece of "technology" there was. We taught sitting by the projector and were 'interactive' when we let the students come to the projector to write on it.
Now, while that is hardly the gadget of choice to most teachers anymore, I DO have to admit AT THE TIME the kids loved it! The loved being able to come and write on the glass. The biggest treat was giving away the baby wipe that was used when I wiped down the glass. The wipe was all tie-dye looking and the kids went crazy to see who was going to win it!
What old school piece of technology was a favorite in your classroom?
