One of our students uses a walker. It was parked in the classroom yesterday afternoon while he was on the floor with the rest of us rolling the ice cream ball. Students have probably been curious all year long about the walker. One got up and tried it, then another and another. They all wanted to know what it was like to walk using the walker. They found out that there are brakes preventing the walker from rolling backward, so they couldn't go in reverse. Another learning experience.
