I haven’t read all the replies, but I thought I would tell you what I did for 1st, starting in ancients. I got these Veritas Press Cards http://www.veritaspress.com/prodinfo.asp?number=000100. I did not use the resources on the back of the Eygpt cards. We read the info on the back and used them as a timeline instead. I did use the resource for Bible on the back of the cards, The Child’s Story Bible by Vos (love). They tell you what pages to read in this.
So for the Bible cards we used:
The Child’s Story Bible by Vos http://www.amazon.com/The-Childs-Story-Bible-Catherine/dp/0802850111/ref=sr_1_1?ie=UTF8&qid=1338908876&sr=8-1.
Journey Through the Bible
The True Story of Noah’s Ark
The Great Dinosaur Mystery and the Bible and Archaeologists Dig for Clues
When we came to an Egypt card I just fit in these books; based on what the back of the card said:
The Usborne Book of World History
The Egyptology Handbook
See Inside an Egyptian Town
Boy of the Pyramids
Mummies Made in Egypt
Tut’s Mummy Lost and Found
Seeker of Knowledge
I hope you find what works for you guys.
