This is version 1 of the tool - NCTM's site has two other versions. I'm not
sure
what is the difference between each version.

I just checked out the versions.

Jeff's link to Hollylynne's work is probably an older version since it doesnt
handle bargraphs for fractions greater than 100%. The revised version below
do!

Nice to see that the illumations site revised her previous work at U. of Va.
