We have the offer of a calculus book for elementary grades. Please
take a look at Don's Web site,


and let us discuss what it would take to get this done up in a series
of Etoys projects. If others think it worthwhile, I will invite Don

I am also proposing that FLOSS Manuals publish the book, and will ask
on the Sugar list whether anybody would like to work on this as a
regular Sugar activity in Python.
