Editorial Review

Readers will find a good basic explanation of weight, how to find it for various objects, and related topics in this Math It! series title. Interesting real-life examples and applications, such as determining whether a suitcase is too heavy to check on an airplane, prevent the topic from becoming too dry. Animals feature in many examples, and their photos add charm and appeal to the book. For instance, the author compares the weight of an animal, such as a rabbit or a giraffe, as measured in both standard and metric systems, and the chapter on units relies heavily on farm animals of different weights. A fun concluding activity involves making a balance from paper plates. Readers will likely enjoy this practical yet lighthearted approach to a weighty subject.
