Pythagoras and the Ratios: A Math Adventure

(4) K-3 Illustrated by Phyllis Hornung Peacock. Neglecting his chores, young Pythagoras helps tune his cousins' lyres and pipes by using a mathematical ratio that yields harmonious tones. With instruments perfectly tuned, the cousins play in unison, wowing their audience. Readers old enough to grasp the math content may not be drawn in by the story's contrivances. Bland illustrations show cartoony scenes of ancient Greece.
