Thank you to Kid Lit Reviews and Bloomsbury Press for sending this book for review. All views expressed here are my own.

If anyone you know is interested in ciphers and cryptography, their use, their creation, or their semi-illustrious history, Ms. Schwartz's book is definitely for you! The histories placed within are not only fascinating (as the title promises), they are also incredibly interesting and informative. The reader learns the why, where, and how of creations, as well as those of brea

"Can You Crack the Code?" is a children's nonfiction book about how codes have been created and cracked throughout history. The author talked about early ways people used to keep a message hidden and then delved into codes. She talked about ciphers, encryption, and decryption at a level that was easy to understand. She talked about the development of different encryption strategies intended to make it more difficult to break ciphers. There was also trivia about specific ciphers used in the past, ...more

My daughter took a DukeTIP class on ciphers and cryptology and adored it. Then we got this book in the mail and she was over the moon about it.

This book discusses different kinds of codes that have been used throughout history and how to crack them. My daughter took the book to her friend's house and they spent several afternoons pouring over the book and working on codes.

This is a fantastic book for kids in the 9-12 age range that enjoy history, codes, ciphers, and cryptography. It's also a gr

CAN YOU CRACK THE CODE? will help you up your game in the encryption world while you uncover the fascinating history and current state of ciphers and cryptography. Filled with examples and encrypted messages, this book will be of HIGH interest for ages 8+.

Not only is the book filled with codes to f

Can You Crack the Code? by Ella Schwartz is an amazingly fun and informative book about all the ways in which people have encrypted secret messages and codes over the course of the world's history. When I first picked this book up, I wasn't expecting it to be as lengthy or as in depth as it was but I definitely appreciated all the new and really interesting pieces I learned about ciphers and cryptography. Not only does the book seek to tell you about the history, but it also offers the opportuni ...more

Let me just say that the subtitle is not kidding. This books covers codes from the ancient Greeks, through Caesar, Samuel Morse, Alan Turing, and up to the current day. Each chapter discusses the methods used to keep messages secure over the ages - from writing them on paper to be swallowed, sharing special code words, supercomputers using prime numbers to create encryption, and even biometric security. There are activities throughout the book that challenge readers to try their own skills at th ...more

This handles the subject incredibly and if you can believe it or not kept me up at night wanting to finish it! I love how it's broken up, the scope of the history starting with Ceasar and going all the way to modern information security/privacy, plus the activities throughout the book and the secret code in the back...I've been doing this NF thing for 2 years now and this is easily one of the best, and certainly one I didn't expect to be so sucked in by.

My only criticisms are it's a bit text he

“Can You Crack the Code?,” written by Ella Schwartz and illustrated by Lily Williams, is an absolutely awesome book. Full of fascinating information and the history of ciphers and cryptography, this book entertained my entire family. We will be talking about and sharing the awesome historical tales in this book for years to come. I even learned a lot that helped me understand my software engineer husband’s job. It is written in a fun and easy to read format with sidebars and illustrations that p ...more

This is a great book for learning about ciphers and cryptography. It's more than just a history, it really goes in-depth into how they work, giving readers an opportunity to try encoding and decoding messages in different ways. It was a little "good guys / bad guys" focused for my preference, but I wouldn't hesitate to recommend it on that basis. I would love to have learned about some examples of nonviolent/nonmilitary usages.

Schwartz introduces a number of different ways that people could hide messages using numbers, switching letters, or even creating machines. Each chapter focuses on one way to create a code and then provides examples for the reader to try. Weaving a bit of fun with history, this is a book I would have devoured as a middle schooler.

Fabulous and highly recommended by this teacher who wants more kids to explore the creative side of engineering and problem solving.

This book carries with it good credibility as the author is a modern day code maker. It reads like an authentic resource for middle readers who want to learn more about code making and breaking.

Schwartz keeps it intriguing and involves appealing language without dumbing it down. The text is part history book and part introduction to the logical thinking necessary

I really enjoyed reading this book. It does a nice job of discussing spies and their various codes. As a history buff, I appreciated the historical background! It doesn't stop with all the historical stuff, though. The book also contains information about computers and the encryption codes we use in our own lives (whether we realize it or not!)

It's fairly in-depth and is definitely meant for older children. I even learned a few things!

Fun "Crack the Code" activities are included in many of the

This is such a fun book for kids! I loved learning more about secret codes, hidden messages and more! I can’t wait to share this with my students and then exchange secret messages based on the codes learned in the book! I’d also like to tie in espionage and the importance of encoding messages, and the impact that has now with data encryption and keeping our information safe.
