This is a great book because it uses pictures to explain estimating, and requires students to guess how many objects are in the picture. I would recommend this book to elementary students, especially late elementary. I think this would be a great book to use in a math classroom. ( )

I enjoyed using this book in the classroom however I felt as though it should be geared to a higher grade level. I felt like my students weren't fully capable to making a educated guess or estimation for all of the pictures provided. However, I did like the open interaction that it allowed for the classroom. It gave the students the opportunity to put on there thinking caps and really observe and do think alouds for each page of the book. ( )

Goldstone’s book models problem solving and reasoning processes by picturing colorful photos of lots of something, posing a question, and providing hints for the reader to arrive at estimates. Hints include training eyes to see groups of 10 or 100, comparing benchmarks of 100 or 1000 to a larger sample as well as clump counting and dividing pictures into grids. Goldstone also provides hints for guessing how long, how tall, or how heavy items are by using comparisons. The book is best taken in small doses, not all at once. Connecting students’ math understanding to the world of work, the author notes the likely jobs where people make use of estimating: writers estimate the number of words written; carpenters estimate lengths of wood; planners estimate crowds when preparing for events; scientists use photos to estimate changes in environment, all of which provide natural extensions for having students engage estimation as do professionals.

Kind of 90s-looking photography, but still a good book for teaching kids how to estimate. ( )

Informational Nonfiction Picture Book
Reading Level: 3.5

Summary:
This is a picture book about learning how to estimate group totals by just looking at the groups. These techniques better help students with their arithmetic.

I checked this book out after reading That’s a Possibility by Bruce Goldstone. Both are great books, but I like this one better. It is colorful and simple. The presentation and photographs are wonderful. Take a look at page 17 to see what an entire box of cereal looks like laid out in a line. How many O’s are in there? Surely, you wouldn’t count every single one. You can get a close answer by estimating.

This book could spark kids to bring create their own pile of items to estimate. Show the class a box of toothpicks to a board and have everyone guess how many are present. Then ask them to use tactics in this book like clump counting and box counting. Compare the answers with and without Goldstone’s strategies. Do you notice any difference?

This is one of my favorite math books. It leaves a lot for children to think about without being too cluttered or confusing. Check it out! ( )

This book may be pretty advanced for elementary kids, however it breaks down using estimation to guess with extremely large numbers. Like how many blades of grass are on a football field. The pictures are a must for this book, and they accompany the rest of the book very well. I believe that it could be hard for elementary kids to understand and older kids may find the book boring. However, it still does a nice job teaching someone the basics of estimation. ( )

A children’s picture book offering three methods (and lots of examples) to estimate large quantities of items:

1) eye training (becoming familiar with what groups of 10 or 100 or 1000 of something look like e.g. candies, coins, small fruits);

2) clump counting (counting a small portion and then multiplying that by an estimate of how many portions are in the group of items); and

3) box and count (dividing the group visually into a box grid e.g. 10x10, then counting the number of items in one box and multiplying by 100).

Fun and helpful. ( )

A book about estimations that includes hints on how to make a good estimation for the picture above. Would be interesting to see students estimations, especially through different grade levels. Nice book to incorporate mathematics. ( )

This my second book review on a book aimed at young readers about the math skill of estimation. The first Estimations by Linn I felt would be useful mostly to teachers as a resource for specific activities to use in class. This book is also categorized as a specialized one with its very narrow focus. I have rated it higher because it has more visual appeal and use for students to access alone. While high school students would not want to use such a "childish" looking book, I could see myself using the book for in class activities. I really like the pages involving estimating size in inches/centimeters and feet/yards/meters. There is also a website I plan to check out (there are estimation games). As a specialized book the content does move from simple to more complex. ( )

This book shows a person how to train his/her eyes and mind in order to make good estimations. The author's note at the end of the book tells the reader what types of people use estimation daily while they are at work. Three types of strategies are discussed, eye training, clump counting, and box and count. All of these will help one to develop good estimation skills. Many examples help the reader learn and use the 3 techniques. Estimation is important in math and knowing how it relates to everyday activities. The exercises used in this book are fun and interesting. A teacher who uses it in his/her classroom could use the book as an activity to practice estimation after the concept has been taught. ( )

What do 10,000 rubber duckies look like? This book gives an excellent, and accurate portrayal of large quantity items. I loved the every day objects the book uses to illustrate this concept. The hints are very helpful too on the bottom of the pages. In a classroom setting, I would read this book out loud first. I would then take several objects and have my students estimate the quantity. Examples include a jar filled with jelly beans, a bag full of marbles, or pen holder full of pens. ( )

Retelling: This book does not contain a single exact count of the pictures it asks you to estimate. You have to use your great estimation strategies to come as close as you can to the answer.

Thoughts and Feelings: Estimation is like a superpower. Counting really large numbers of things seems impossible, but if you think about what IS possible, what you CAN say, you get closer and closer to the answer. It's like an exercise in positive thinking. LOVE IT!

Estimating is a very difficult task for people of all ages. This book is a GREAT way to help children (and adults!) learn estimation skills.

This book has great photographs. I love the bright colors and the math concepts that are taught.

Really neat look at estimating and teaching how to estimate large numbers of things. It gives examples from popcorn to the heights of trees.From liquids to the weight of dogs. Very thorough. ( )
