School Library Journal - 02/01/2017 Gr 3–5—Adler and Miller (Circles; Place Value) team up again to introduce the concepts of estimating and rounding to young readers using relatable, practical examples and appealing illustrations. Estimations as "approximate answers" are first defined as acceptable responses to questions whose exact answer is continually changing, such as the population of the United States. Rounding is then presented as a tool that can make estimations, such as the cost of groceries or the product of two double-digit numbers, easier. The artwork reinforces the conceptual examples found in the text and features three unnamed children and five anthropomorphic dinosaurs drawn in a pleasing cartoon style. Important terms are shown in bold but are defined only within the text; there is no glossary or other back matter. Although the concepts are conveyed clearly, the subject matter, density of the text, and smaller font size make this selection much more likely to be helpful to students when shared with a caregiver or educator in a one-on-one or small group setting than when read independently. VERDICT Highly recommended for classroom and school libraries and for public libraries where Adler and Miller's previous titles are in use.—Kacy Helwick, New Orleans Public Library - Copyright 2017 Publishers Weekly, Library Journal and/or School Library Journal used with permission.

Booklist - 04/15/2017 What’s not to like about this guide to estimation and rounding numbers? Cartoon kids and dinosaurs walk readers through estimation and rounding exercises, offering written explanations, math problems with solutions incorporating number lines, charts and graphs, and humorous scenarios that provide visual reinforcement (T-Rex ate about 460 cookies. Now he weighs about 4,200 pounds). The content is aimed at students grades three and up, and provides a sufficient range of examples so that readers should walk away with a pretty good understanding of these two math concepts. The small percentage of students who aren’t all that enthusiastic about this volume may find the picture-book format and goofy illustrations a little juvenile. Be that as it may, most kids who are struggling with math will welcome help, so why not provide assistance that is straightforward, accessible, and fun? Never condescending, this friendly guide should be a worthwhile addition to school and public library shelves. - Copyright 2017 Booklist.
