Attn: All [Computer-Savy] Math Teachers

I could help some more if I knew what level she was teaching, but for lower level stuff, there are some good programs out there that are test/worksheet generators that have some graphs on them. The ones I used were from this website:
http://www.kutasoftware.com/

I have both the Pre-Algebra and the Algebra I

For higher levels (if she teaches high school calculus or college courses) you could look into these:
http://www.ptc.com/products/mathcad/ Program is called MathCad

http://www.wolfram.com/mathematica/ Program is called Mathematica

Personally, I either just used the Kuta Software to make coordinate planes or I drew my own for regular data charts.

I also occasionally used an online program called Study Island. It was a program that our school already had/paid for, and it has questions formatted like standardized tests for every state. You can tell it to make the questions fill-in-the-blank as well, and when you "create" a worksheet, it opens in Microsoft Word, & you can cut and paste into your own document. I think it requires some sort of paid subscription, but I have no idea how much it is.

I'll look around some more and see if I can find anything more useful!

Look at Visio. I have been using it for years. Do not need anything special just your computer and mouse.

Well...you can use data already entered in Excel & use graph wizard to do various options of charts/graphs for the selected data...do you think that's what she means?
(Sorry--not a math teacher but I do use excel quite a bit.)

She might be talking about Geometers Sketchpad. http://dynamicgeometry.com/

(Check the pricing for the student version.)

It's really nice that you're offering to get this software for her so that she can teach math more effectively for her students. It's especially nice if her school does not pay for teaching resources like this. Most teachers spend so much of their own money on school materials, and expect none or very little of it to get reimbursed.
