More About the Author
Starting with the Great Estimations series, I've had a lot to do with how my books look. For those two books, I was the photo stylist, which meant I got to spend hours counting and arranging macaroni elbows, google eyes, fake cockroaches, and rubber ducks. And then beginning with 100 Ways to Celebrate 100 Days, I started taking some photos for my books, too. (I don't have much room here, so if you see a photo of something like an elephant in one of my books, chances are pretty good that I didn't take that one.)
Books have always been a big part of my life, from buying dusty old paperbacks in any used bookstore I could find to my first job, shelving books as a page at the Shaker Heights Public Library. I even love that word: I was a page!
In 2002, I decided it was about time I learned to speak a foreign language, so I started taking Spanish lessons. One of the biggest joys of this ongoing project/struggle has been learning to read literature in another language. These days I feel just as proud and excited to finish a book in Spanish as I did when I first read Half Magic, Alice's Adventures in Wonderland, or The Once and Future King.
Oh, about those textbooks. I've written thousands of pages in pretty much any subject you can think of, from reading and math to social studies and science. I try to make them as interesting as possible, but even so, I'd like to officially apologize for any math problems or grammar worksheets that any of my readers found particularly annoying.

While I don't foresee many repeat readings, there is a lot to like in Great Estimations.
A must for the math section of any kid's bookcase or any teacher's classroom.
The clear, colorful photos in Great Estimations are more than just picture puzzles. From pencils and gummy bears to a flock of penguins and a pile of rice grains, each page offers progressively more complex groups of items. How many pretzels are there? How many bunnies?
In brief, conversational text, Great Estimations walks the reader through the art of estimating quantities quickly and easily. No exact answers are given; the goal of each puzzle is to reach a "reasonable estimate," coming close to the real number.
The book begins with eye training: learning to recognize groups of 10, 100, 1,000. Interesting pictures of simple objects make this easier than it sounds.
Next come specific techniques. Clump counting includes counting by tens and looking for patterns. Box and count is another way to get a handle on very large groups.
Estimating has practical applications. For example, how much is your penny collection worth? No need to count every cent; weigh the total and estimate!
Although presented in picture-book format, this attractive handbook has a wider potential audience. Young children who can't count yet will enjoy the detailed pictures and start to develop concepts of "few" and "many." The tips on estimating will be most helpful to someone who already understands multiplication and counting by fives and tens. Adults who consider themselves "math-challenged" will be delighted to discover that estimating is something they can do well.
A final section on "greater estimations" moves from objects spread on a flat surface to three-dimensional estimating. Now you can estimate the number of jelly beans not just on the book's cover but in a fishbowl. It's a skill that could be very handy for winning prizes at a fair, festival, or grand opening.
It shows how to count a representative sample of objects, and then reckon how many groups are there. For example, consider a box of evenly-spilled elbow macaroni. One should count out 100 elbows, and visualize the area covered by these 100 elbows. From then, one should see how many multiples of area there are. For instance, if the total area covered by the spilled elbow macaroni covers eight times the area covered by the 100 counted elbows, then there were 800 elbow macaroni pieces in the box.
To count the number of jellybeans in a jar, one could count how many jellybeans are found in the first frontal layer of the jar, and then multiply that by the number of layers in the jar.
The author also shows how to measure the amount of objects per unit area (for example, per square inch) and then multiply it by the number of square inches.
