Annotation: "Diamonds are similar to squares, with their sides of equal length, but they look a bit "squashed." Readers will recognize this special shape in the many bright photographs of this accessible text, which also encourages them to build new vocabulary. They'll see diamond-shaped kites, cookies, and signs, and learn to spot diamonds in patterns as well. As they develop their knowledge of this elementary geometry concept, they'll understand how this aspect of math applies to real life. A final question asks readers to identify a diamond in an image, providing a final assessment opportunity"-- cProvided by publisher.
