The figure below is called Mr. Short. We used large round buttons laid side-by-side to measure Mr. Short's height, starting from the floor between his feet and going to the top of his head. His height was four buttons. Then we took a similar figure called Mr. Tall and measured it in the same way with the same buttons. Mr. Tall was six buttons high.
