I've had a few math tests laminated to turn them into dry erase sheets for math drills. The boys like to compete to see who can finish first, who can get the most right. It's been a great help to our everyday math work.
"Can you laminate anything?" one child asked, turning the sheet over and scheming about how this new tool might prove useful to him.
"No," I said, "only paper things."
"Wow," he replied, "You can laminate origami!"
