How long is the world's longest earthworm? How tall was a brachiosaurus? What's the average diameter of human hair? What's the circumference of the earth at the equator? Now you can discover the answers to these and other fascinating questions about math. Packed with illustrations, Math for Every Kid uses simple problems and activities to teach you about measurements, fractions, graphs, problem solving, and much more! Using activities that relate math to everyday life, this book will help you feel comfortable with math--right from the start. You'll make a sun clock, create a thermometer from a straw, race a paper boat, grow your own bean plant, and even play a game of ring the bottle. Each of the many problems and activities is broken down into its purpose, a list of materials, step-by-step instructions, expected results, and an easy to understand explanation. Every activity has been pretested and can be performed safely and inexpensively in the classroom or at home.
