Mistakes That Worked

January 1, 2017

Gr 3-5-All of the inventions mentioned in this book were the result of accidents. Frozen dinner rolls, cheese, Velcro, piggy banks, X-rays, and penicillin were all "oopsies" that turned into popular everyday items. Sections cover food, clothing, toys, medical inventions, and more. Significant changes have been made to the original version of this title, published in 1991. Recent statistics replace outdated numbers: how much cheese people eat, how much Coke has been consumed, how many potato chips are sold, etc. Previously, additional information or recipes were included on the page. Now, they are given their own space, making them easier to read. Gone are the full-page, color, pen-and-ink illustrations. Smaller, black-and-white versions are inserted among the text. These images comically portray the unexpected benefits that can come from making mistakes. VERDICT Nicely updated; consider to replace the older edition.-Sandra Welzenbach, Villarreal Elementary School, San Antonio
