We were sent a copy of this little book from the Critical Thinking Co to review. It's a 42 page book full of puzzles that require deductive and mathematical reasoning skills to solve. Each puzzle has a logic-puzzle style chart to break a secret code to uncover a quotation. You can see a sample here.
This was a fun book. It is reproducible, so I can give copies to Kaytie and later, when the younger kids are ready, they can do it, too. I had to give Kaytie a little help to start off with, but she caught on in the middle of the first puzzle. After she was done, I sent her off to play and did a few of the puzzles on my own. This is a great first step on our way to a logic-filled future!
Kaytie's opinion: It was fun and it was hard. I want to do more. :)
DISCLAIMER: I was sent a copy of this book for free for the purpose of this review. All opinions are honest and are my own.
