Learning to make strong guesses about numbers and quantities is just about the most important skill any mathematician can learn. But figuring out a number that makes sense can be overwhelming unless you know a few tricks. GREAT ESTIMATIONS by educational writer Bruce Goldstone helps take the mystery out of guessing. Readers will feel more comfortable estimating as they turn each vibrantly illustrated page and learn clever but simple techniques for coming up with answers that make sense.

Beginning with a cover jumbled with jelly beans, the reader is led through progressive lessons with a question, a statement, and a hint or two on each set of pages. Engaging examples including collections of toys, candies, coins, seeds, beans, doll shoes, and people in a pool. This common sense, clearly written book proves that math can be fun and offers entertaining, invaluable lessons that will make any reader feel more secure in the world of numbers.
