Editorial Reviews

...the exciting conclusion is a true group solve, with the kids deciphering the overall metapuzzle, accomplishing as a team what they never could have solo. Math, logic problems, and puzzles solvable by readers who want to try, all in a diverting chapter-book mystery.

Kirkus Reviews, April 1, 2021

As with the other “Math Kids” books, author David Cole has left readers with a novel that will keep them wondering until the very end. The Math Kids: An Encrypted Clue is full of interesting fact and figures, problems and interesting historical notes. ... these books are as interesting for adults as they are for children. If you have not already found the value and the mysteries in mathematics, just read these novels to your children. Highly Recommended
