Measuring Penny

For a homework assignment, Lisa is asked to measure something using standard units (like inches, feet, teaspoons, pounds, and minutes) and nonstandard units (such as paperclips, bricks, marbles, pencils, even toes). Lisa decides to measure her dog, Penny, and discovers that Penny's nose is one inch long, her tail length equals one dog biscuit, her paw print is three centimeters wide, her ear is as long as one cotton swab, and that Penny can run from her bed to her food bowl in six seconds. Illustrated with acrylic paintings.
