Great Estimations by Bruce Goldstone
2006, Henry Holt and Company, 32 pages, hardcover
Great Estimations is an eye-popping introduction to the art of, or perhaps the science of, mathematical estimation. Bold colors and clear photographs are used to demonstrate simple, concrete approaches to an abstract mathematical concept. Penguins and pennies. Jelly beans and elbow macaroni. Plastic shoes and paper clips. Practice the techniques for eye training and the methods for clump counting and box counting. Then you can estimate how many of them there are - maybe before your young student does! If you get stuck, use the hint box at the bottom of the page for suggested methods, answers, and applications. This is a winning addition to your living math bookshelf!
