Imaginative comparisons help children comprehend various units of measure. How fast is 120 kilometers per hour? How heavy are 4 tons? How loud are 150 decibels? Units of measure are abstract--until, that is, they are contrasted with other quantities. The entertaining juxtapositions in How Big is Big? How Far is Far? make dimensions and measurements more comprehensible for children. The book features amusing comparisons that make units of length, distance, weight, speed, volume, and time easier to grasp. The Queen of England's crown, for example, weighs more than 100 portions of cotton candy. Some babies can cry as loud as a jet fighter sounds when it takes off. When the world's oldest living tortoise was born, there were no electric lights, telephones, cars, or airplanes. How Big is Big? How Far is Far? is full of amazing facts for children thirsting for knowledge. Intelligent and witty illustrations by Jan Van Der Veken help young readers better understand how large, far away, heavy, loud, or old something actually is when they come across a unit of measure.
