We're Sailing Down the Nile by Laurie Krebs and Anne Wilson*

Although we are studying Ancient Egypt, I had my eight year old read this simple, rhyming book because it had a fabulous map of the Nile and cities and historical sites situated along it.
The bulk of the reading is in the back with tons of information about gods, time periods, social classes, occupations, pyramids, mummies, hieroglyphs and lots more.  It was interesting too to read about the Aswan Dam.
*Highly recommend.
