Great Estimations

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! This oversized edition is perfect for sharing with a group of children.
