Critical Thinking Company: Crypto Mind Benders

Well, this was a fun little item to review! I appreciate the Critical Thinking Company products, and they recently sent the TOS Crew a variety of items to review. We received "Crypto Mind Benders".

This slender volume is filled with 30 puzzles(And their solutions) to exercise the logic muscle of your children. :) When Eldest picked up the book as it lay on the table, she commented "Oh! This looks like fun!". Middlest was less excited (That word "mathematical" on the cover did it for him... ;p), until he learned how the puzzles worked~ now HE thinks they are fun as well!

This is a wonderful thing, as lately we have been working on getting Middlest to think more logically, and including math in the equation is a bonus from my perspective.

Here is a sample activity~ use the equations on the left side to fill in the chart, and logically deduce which numeral = which letter.

After each puzzle on the page is worked, the letters are placed into the appropriate blanks in the cryptogram to discover a famous quotation.
 (You can find and print this sample activity from the product page's "click to look inside" link)

The symbols used in the clues are identified in the front of the book, and the first 2 pages are a "Sample activity" that walks the student through the process. Very simple to pull out and use, but the problems definitely get more challenging.

Crypto Mind Benders are one activity that I can just lay out, and my kids jump to do them~ I don't even have to ask. :) (And, yes~ I am a puzzling mom that enjoys this sort of thing as well).
