Downloadable math practice or enrichment?

[moominmamma]

I'm working part-time more this year and my 9-year-old needs to come along and kill time while I'm busy. She has a laptop at her disposal and enjoys stuff like KhanAcademy, but we have no internet where I work. I'm wondering if anyone knows of any free or cheap downloadable programs for math practice or enrichment that she might be able to make use of. Or really anything academic ... critical thinking puzzles, sciencey stuff, I don't know what all. She has games to play and books to read, but she'd also like to use her time there for some academic work and has asked if there's anything she could load onto her computer.

She's probably at a 7th or 8th grade level. She finished Singapore Primary Math a year or so ago and has worked through most of Ed Zaccarro's "Challenge Math" book. We're mostly enriching and consolidating before moving ahead fully into high school level stuff. So I guess in American terms she'd be pre-Algebra-ish?

Anyone have any suggestions?

For printing or software?

Www.Mathmammoth.com has single subject books for a few dollars. I think you can type directly into the pdf file or print.

Www.krazydad.com has free math puzzles to print.

Thanks. Geogebra looks interesting. I wish it was easier to see what the content was without downloading and installing the whole thing, but I think we'll check it out.

this is a totally random aside suggestion, but might she enjoy programming? That's fairly mathsy. There are instruction books aimed at kids for VBasic and I think C and other languages, another option might be HTML or JavaScript? Just a thought. I did a lot of programming back when I was around her age and really enjoyed it from a mathsgeek pov.
