Three years ago, I held a great, week-long Spy program at my library for Summer Reading. The kids went berserk for it; I had a blast planning and running it, and books like Can You Crack the Code? make me think it might be time to hold a program like that again. Ella Schwartz has come up with a nice history of codes, code names, and cryptography for middle graders, with loads of pictures, informative sidebars, and activities to keep readers on their toes. Famous moments in cryptography history include the Caesar Cipher, invented by Julius Caesar, the Arnold Cipher, used by the infamous Benedict Arnold, and the Enigma machine, used by the Germans during World War II; the machine that gave them the upper hand until a team of British codebreakers at Bletchley Park finally broke the code (shout-out to computer scientist and codebreaker Alan Turing). Want to know why you have to generate a strong password, obnoxious as it may be? Check out the “Can You Hack the Bank?” activity and you’ll be changing all of your passwords. A final challenge has readers going through the book to solve one last cipher. There’s a comprehensive bibliography and the book is indexed, making this a nice volume to have on your shelves.
Display this with the Book Scavenger series, the Mr. Lemoncello’s Library books, the Secret Coders graphic novels, and – naturally! – the Girls Who Code books, both fiction and nonfiction. Brightly has a good post on fiction with puzzles and codes.
Now, if you’ll excuse me, it’s time to revisit some of my old Summer Reading plans… I know this year’s theme is A Universe of Stories; maybe I’ll just use some codes to send them into space! Great escape room ideas in here, too. All around fun for your brain-teaser-loving readers.
