Just wheels, in a short, fast-rolling rhyme--""One wheel/two wheels/three wheels/ Four. . . Meals on wheels,/ Squeals on wheels,/ Coats,/ Boats, / Floats on wheels. . ."" --accompanied by rapid soft-pencil sketches of a circus bear on a unicycle (one wheel), a hot dog cart with vendor and small customer (meals on wheels), a fire engine (clang on wheels), etc. It's bouncy enough to limber up a preschool session, tho it's only one little rhyme.
