The History of Counting ~ A great living math book

We read this book, The History of Counting by Denise Schmandt-Besserat this morning during our math time. We all thought it was quite interesting, blending history and mathematics. The author, who is also an archaeologist, explains how counting evolved from little marks on bones done by hunters and gatherers to our Arabic numeric system of today.
Here is a cute idea to make your own little abacus with Popsicle sticks and beads!
