Adler, David A. Triangles. Illustrated by Edward Miller. Unpaged. 2014. Holiday House. $17.95. Nonfiction picture book.
While the author explains all about triangles and their angles, the illustrator presents us with two kids and a robot building another robot. The book starts by explaining angles, covering how they are named, measured and classified. It then moves on to types of triangles. By the end of this short book, the kids have constructed a new robot mostly out of triangles, and the author has identified all the congruent and similar shapes on its body, and labeled all its angles.
The illustrator uses a retro color scheme of mostly turquoise, red, and yellow which gives the book a classic picture book feel, but the text is strictly informational. Most students may need lots of time and practice to master all the information presented here, but the illustrations are well labeled and the book would work well as a review for any class learning about these concepts.
