I finally remembered my camera!
Katie started out with the glider again. During the lesson, the instructor pulled the children along with a jumprope. At first, Katie declined, knowing that she'd have to give up the glider. After she saw the other children having fun being towed, she cast it aside and allowed the instructor to tow her. She didn't go back to it for the rest of the lesson. After the lesson, however, she skated off and on with it. She found she could really pick up speed holding on to the glider.
I made this video just before I made them get off the ice:
