Let's Estimate: A Book About Estimating and Rounding Numbers

I like a lot of David Adler’s books, and was really disappointed in this one. It looks like it was done very quickly and sent out without being looked over well. My 2nd grader figured out that the arithmetic is wrong on one of the pages (see pic) and wrote a note to the librarian. A few other graphics don’t seem to match the text, and other things are confusing (see other pictures). It got two stars because there were some helpful things (e.g. that when someone asks your age, the answer you give them is rounded).

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.

I appreciate the effort writer puts on this book. It may be helpful for some kids. For both me and my kid, it felt overwhelmed and made things more complicated. We have couple of this series and my kid ended up give up on reading them.
