About the author
David A. Adler
404 books205 followersDavid Abraham Adler is an American children's author. He was born in New York City, New York in 1947. He graduated from Queens College in 1968 with a bachelor's degree in economics and education. For the next nine years, he worked as a mathematics teacher for the New York City Board of Education, while taking classes towards a master's degree in marketing, a degree he was awarded by New York University in 1971. In that same year, a question from his then-three-year-old nephew inspired Adler to write his first story, A Little at a Time, subsequently published by Random House in 1976. Adler's next project, a series of math books, drew on his experience as a math teacher. In 1977, he created his most famous character, Cam Jansen, originally featured in Cam Jansen and the Mystery of the Stolen Diamonds, which was published that year.
Adler married psychologist Renee Hamada in 1973, and their first child, Michael, was born in 1977. By that time Adler had taken a break from teaching and, while his wife continued her work, he stayed home, took care of Michael, and began a full-time writing career.
Adler's son, Michael S. Adler, is now the co-author of several books with his father, including A Picture Book of Sam Adams, A Picture Book of John Hancock, and A Picture Book of James and Dolly Madison. Another son, Edward, was the inspiration for Adler's Andy Russell series, with the events described in the series loosely based on adventures the Adler family had with Edward's enthusiasm and his pets.
As of November 2008, Adler has three sons and two grandsons. He lives in Woodmere, New York.

A bit monotonous, Let's Estimate runs the audience through world problem examples to teach how to estimate and round numbers. Illustrator Edward Miller uses kids and dinosaurs to capture the interest and imagination of the audience. Adler's examples are both useful and practical, showing how this mathematical concept might be applied in real life to the audience's benefit. One example, however, estimates the number of people in the United States. While this estimate will be accurate for a few years, it will easily date the book soon after. Other examples include the length of the United States from coast to coast, the distance to the moon, and going grocery shopping. This book might be best taken a page or two at a time to avoid overwhelming a bored audience, but could serve well in one-on-one interactions.

Need a math refresher on estimation and rounding? Learning to estimate & round? Then this book is for you!
Parents & Teachers! This is an excellent book to read to your kids. (Parents! This is a great refresher.) I used this book during the summer to start my second grader on the right track for the new school year. Estimation and rounding is a key component of the second and third grade math curriculum. This story opened a great conversation with my kiddo and I was able to teach him how to round and estimate in just a few lessons at the kitchen table.
Why do we estimate? This book explains in easy to understand examples, why we estimate and round and how to do it with simple, easy to understand procedures. The book is full of examples and wonderful illustrations.

An introduction to estimation and rounding for kids, including the difference between the two and how and why you might want to use these tools.
Adler has become the king of math concept picture books. He does a great job in this one of breaking down these concepts in ways that kids can easily grasp and he provides several pages for them to practice them after they've been introduced. He also makes the concepts relatable to real life and when and why you might want to use each. The illustrations help further clarify and keep kids entertained along the way. Recommended for math teachers and kids who need these concepts presented in a different way.

Some interesting information about estimating which may be helpful to some students.

The format is geared towards a younger audience so isn't as helpful for the content.

Through repetition, estimation and rounding is covered and explained very well.

This is a great book to explain estimation and rounding up in mathematics (and life) to school-agers. It may be a little over the heads of younger school-age kids...buuuuut if they love math then it may just be their thing!

David Adler is a master when it comes to explaining things, and he hits one out of the park again with this book on estimation. Cute digital illustrations, featuring dinosaurs (who doesn't like dinosaurs?) accompany clear and cogent text that explains how and why we estimate. Adler explains the difference between estimation and rounding. Clear examples of both are given, along with instructions. The text is a little wordy, but all of the words are necessary for a clear explanation. School libraries will want to have this in their collections.

Featuring digital illustrations and his usual straight-forward and engaging examples and explanations, David A. Adler tackles the important mathematical skills of estimation and rounding numbers. Although the two are clearly not the same, they can work together, and he gives young readers a vigorous numbers-related workout with pizza, distance, and even grocery shopping. Readers are encouraged to estimate the number of steps they will need to take from one end of the block to the other end and then count how many steps they took in order to compare the two and notice how close or how far off the estimate was. I really appreciated the opening pages that discussed how it is impossible to state the exact population of a country since it's always changing; nor do we say our exact age, down to the month, week, and day so these are concepts that are important to cover. I always wondered how experts came up with the number of attendees at public events. I've said it before and I will say it again, David A. Adler is a treasure, and his books are absolutely essential for a classroom math library.

A solid introduction to estimation (and rounding, with emphasis on the difference) for kids. With dinosaurs!
Does a really good job of explaining why people might estimate something, and a few ways of doing so. Gives lots of examples to help kids grasp the concept and get a little practice.

Everyone knows that Adler is a master at taking complicated concerts and breaking them down into smaller easier to understand parts. I love that Adler can find ways to clearly explain the concepts and does so with humor and fun as well as with graspable examples. For example: How much pizza do you need for a dinosaur party? Kids who are struggling to learn how to estimate or round number will find it so much easier to understand after they read LET'S ESTIMATE: A Book About Estimating and Rounding Numbers. I found myself thinking that I wish I had this book when I was growing up because it would have helped me so much with these mathematical concepts. There are easy to understand charts and graphics that help children learn how to be successful when rounding or estimating. I think this is a must for all children learning these concepts because Adler is a pro at teaching. I just cannot say enough how fantastic that this book is...a story with fun, entertaining and engaging learning concepts.
5 HUGE stars!
