The book was by Edgar and Ingri D'aulaire.
Alexa's on top, Taylor's map and Skylar's timeline.
Each girl does the same lesson to a different degree. What I mean is, Alexa does coloring pages, etc, but the facts are typed up for her and we go over them as review, but she isn't expected to write anything. Skylar usually has the option of coloring or drawing, she does the maps and the writing part. I usually have it ready for her to copy. With the timeline, Alexa didn't do it, Skylar did it with my help and the info. was already printed and it became a cut and paste into the right place project. Taylor has to write the info. and make the timeline herself. Of course I am always here for questions, or at least nearby.
