Galloping Through Gallons From Jan P. Kennedy, a special education teacher at Woodruff Elementary School in Woodruff, South Carolina: "Make a 3-D mobile visual to teach the equivalent measures of pints, quarts and 1 gallon. Begin with a plastic gallon milk bottle attached to a hanger with yarn. Next, attach 4-quart milk containers to the bottom of the gallon bottle with yarn. Finally, attach 2-pint milk cartons to the bottom of each quart container. Students can readily see how many pints in a quart, how many quarts in a gallon, etc. This visual will be learned more quickly than a repetitious series of written equations and your students will be able to answer questions with mental math rather than pencil-and-paper math. A similar mobile can be constructed starting with a yardstick for representing yard, foot, inch."
