Groovy Greeks by Terry Deary, Martin Brown

Apparently the Greeks (we are talking about the Ancient variety) were a rather groovy bunch. The boys didn't start school until they were seven and girls didn't have to go at all. Greek children invented all manner of cool games just for something to do, and the grown-ups invented the Olympic Games and made the men run naked.
As Terry Deary points out, though, in his Horrible Histories: Groovy Greeks, things were not always quite as jolly and some of the more disturbing facts unearthed in this funny and clever alternative to the history book are actually quite, well, horrible. From Goodreads.

The only reason I read this short story is that it was in the same book as Percy Jackson and the Sword of Hades. This Groovy Greeks story is meant as a history lesson for very small kids.
