What in the World is a Ton? And Other Weight & Volume Measurements. ABDO Publishing Company, 2013.
The story connects real life objects to their measurement in weight, volume, height, and ton, as well as several other measurements. The author is credible since she uses real objects like an ice cream carton measured in pints. The measurements are made by children which is easier for another child to relate to. The illustrations are real people with real objects. I think this book would integrate fabulously with a 2nd-4th grade math lesson on measurements. There's even a mini quiz and glossary at the end! However, the children used are not very diverse.
