How many jelly beans are on this book's cover? Don't count--estimate!
If someone handed you a big bowl of jelly beans, how would you figure out how many there are? You could count them, one by one--or you could estimate. Do you see more than five jelly beans? Less than a million?
This unique book will show you how to train your eyes and your mind to make really great estimations--by making estimating into a game. Jelly beans are just the beginning!
