Highly Recommended. FIVE STARS. "As he does in the eight other books in “The Math Kids” series, author David Cole gives readers a chance to solve the problems along with the Math Kids, and the book has an appendix at the end that has the most interesting information. Though the book’s recommended age is stated as ages 9 to 12 or grades 4 to 7, younger students will love the action-packed stories, and adults will enjoy reading these books to these younger children. I know I do."
Description
Hidden cameras, secret operations, and new math concepts await in the Math Kids' ninth adventure!
Justin has been accused of stealing from the comic book shop! To earn back the trust of his parents and the store manager, he'll have to work at the shop for four whole weekends. And that puts a damper on his plans to play video games and hang out with fellow Math Kids, Jordan, Catherine, and Stephanie.
With the end of summer approaching, the four friends realize that finding proof of Justin's innocence is their only way to save Justin's good name. To get it, they'll need to uncover who really stole the comics. Their primary suspects are the two older boys who accused Justin, but catching them red-handed will require more than just teamwork.
Solving this problem will require knowledge of proofs and patterns, and if the Math Kids aren't successful, it won't be just Justin's reputation at risk.
