A frog sits on numbered lily pads. It starts on 8 and counts on, hopping forward and saying the next number each time (9, 10, 11), and each hop is shown as one more. Then it starts on 15 and counts back, saying the number before each time (14, 13, 12), with each hop shown as one less, and the video ends on the recap: start at any number, then count on or count back.
