Crypto Mind Benders®: Famous Quotations

Crypto Mind Benders®: Famous Quotations

Deductive and Mathematical Reasoning Skills

Grades: 3-12+
Subject: Mathematics 

     Some of our lessons are completed in the car. We tried using this book that way, and although it led to a lot of laughs I don't recommend it for "car schooling." I do recommend it for what it is designed for; it: "develops algebraic thinking and teaches basic programming operations." My kids worked through several of these together and had fun with the challenges.

     Each page (which can be copied for use in your family) is a stand-alone mind bender activity. The problems progress from simple in the beginning (mainly ordering numbers based on greater than and less than) all the way to complex equations in the last pages. Children reason through the activity to determine which numbers represent which letters. Graph charts are included for more visual input in that part of the task. Then the letters are plugged into a famous quotation to be deciphered and pondered. (The cover picture closely resembles the activities inside.)

     This 48 page student book also includes the answer key; it is available from the Critical Thinking Co. website for $10.99 as a paperback or e-book. This is just one of many workbooks that our family has enjoyed from The Critical Thinking Co. Other team members also received Balance Math Teaches Algebra, Interference Jones: Beginning, and Mathematical Reasoning Level F. Be sure to check out other reviews at the TOS Homeschool Crew Blog.

     Disclaimer: As part of the TOS Homeschool Review Crew, we received the aforementioned book for this review. Opinions shared are my own with family input. 


  1. Ooh, this one is right up my alley! I love this kind of thing-- love the challenge!

  2. I like this kind of challenge, too, and enjoyed doing it with the kids.
