Gr 2–4—Readers with a sense of humor and a love of interesting facts will find silliness in this series of joke books. Using soft, earthy colors alongside photos, art renderings, and cute illustrations, titles offer approximately nine chapters with four jokes per chapter. Each book follows the same format: a page with jokes followed by a page with a fact about the chapter topic, like, “Archaeopteryx is considered one of the earliest birds on Earth,” (Laugh-Out-Loud Dinosaur Jokes). The jokes are written using speech bubbles with questions and joke answers in alternating colors: “Why did the star go to college? To get brighter!” (Laugh-Out-Loud Space Jokes). Although some of the jokes includes plays on words that may need explaining, they are separated by topics to give a better understanding. The back matter includes a glossary, an index, and more places to find jokes. VERDICT A silly series of jokes for elementary school readers.
