Publisher's Synopsis
Imagine how difficult life would be if you couldn't count things, measure anything, do any calculations or be precise about time, distance or price.
This series takes readers (Ages 8-12) on a historical journey, examining how people coped in the past and how they developed ingenious ways to make life safer and less unpleasant. Each book features full-color cartoon-style illustrations and hilarious speech bubbles to heighten interest, making the series attractive even to reluctant readers.
