I thoroughly enjoyed getting to know Charlie Numbers. This was a great middle grade novel that was entertaining, had an interesting plot and a setting that involved a paper plane contest. How fun would that be to compete at building paper airplanes. I'm not a science whiz so I can't speak to the actuality that a paper plane could fly 180 feet or more; it certainly was believable.

In reading this, it was apparent that Charlie had another adventure that tested his mathematical skills yet this book completely stood on its own. And I look forward to more adventures of Charlie and the Whiz Kids.

The publisher provided me with an eARC. This was my honest review.
