Was just looking at these:



I worked with a student with a student using the book....The Story of Numbers....How Mathematics has shaped Civilization...seemed to be a book that was at about the right level ...by John McLeish...
She really enjoyed it,....we did puzzle how the babylons taught their children to do fractions in a base 60 number system....
