It's available from Sunburst - see

Also there is very thorough analysis of the program at

Don't let the cute title lead you astray. The full title is Green Globs and
Graphing Equations which means it includes a tool component. This is one of the
best math software programs  of its kind ever written. Sharon Dugdale and her
team that developed it in the early 80s at UCDavis thought very carefully about
how to craft it.

I'm not sure I understand what you mean. Using software does not say anything
about the value of other approaches (including paper and pencil). Choosing the
right tool for the job is always an important consideration (otherwise you
wouldnt participating in this technology tool forum.)

But also it is important to choose the right context for the right job. I wrote
a story about Guillermo - an 8th grade student - which demonstrates how a
particular context made all the difference. See
