Lucille Wallower 1965
I found this little gem at the used bookshop a few years ago. It's in pretty rough shape and was obviously used by a school, but has lots of neat information in an easy to read elementary format.
Not too far from us the Wissahickon Valley Watershed sometimes offers a family educational day about the Lenni Lanape Indians that used to live in the area. We went once and the kids learned to shoot a bow and arrow, saw the different food the Indians ate and a woman of Lenni Lenape heritage came and demonstrated how they dressed and their customs. It was a neat program.
This book also has ideas for things you could make or try. It's a nice instructional tool as well as an interesting read.
