I asked, “I wonder what would fit inside?”
He looked at me curiously, not knowing where to start. I suggested we look in the baskets of math manipulatives and see what might fit inside. He examined each basket, and selected several objects to try – a rubber car, a small plastic cat, and a counting bear. None of them fit.
I brought over a basket of art materials. He searched through it, and chose some pompoms, which to his excitement, fit inside. He pushed pompom after pompom into the tubes.
But then, the question became how to get them out?
He tried pushing them with his finger, and then with a popsicle stick. Then he tried a pipe cleaner, which easily pushed the pompoms out to the other side.
