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

This year in third-grade math class I learned about estimating and rounding, so I was very excited to read this book. One thing that is explained in the book is the difference between estimation and rounding: “When you estimate, you make an educated guess at an actual number. When you round a number, you change it so it’s easier to work with the number.” In this book, the author and illustrator show the ideas with pictures of funny cartoon dinosaurs. This makes the book easier and more uncomplicated. The book is not really a fiction story with a plot; instead, it uses different situations to show the reader examples of how math works in real life. For instance, one imaginary situation demonstrates how someone in a grocery store might use rounding when they are buying cereal, milk, and bananas. There are little characters with word bubbles, and I liked their comments. I am going to give this book to my third-grade teacher, Ms. Wright, so future students of hers can read this book!
