Here are some links about TI calculators (especially TI-Nspire) I find most usefull:
- Texas Instruments' oficial site: the first place to go look for information on TI's calculators (software, updates, manuals, etc).
- TI-Nspire's oficial site: TI's site devoted exclusively to the TI-Nspire family.
- TI-Nspire's user group: a discussion group packed with useful information and lots of files to download.
- Univers TI (in French): very comprehensive website built by Nspire's users in France. Some amazing files available to download.
- TI-Bank (in French): a community website with a huge program library, including some Nspire documents.
- TI-Calc.org: probably the biggest collection of software for TI calculators. If you need a particular program for a TI calculator you'll probably find it here.
- Lafacroft: a very useful site, featuring all the files published on the Google group in a nicer way.
- Steve Arnold's site: lots of resources and articles about TI-Nspire for the absolute beginner and also for advanced users.
- Marc Garneau's (aka Piman) blog: documents explaining some of the most extraordinary tricks with TI-Nspire
- John Hanna's site: some of the most impressive TI-Nspire documents can be found here.
- Sean Bird's webpage: great activities and programs for TI-Nspire;
- Handheld Geometry, a website maintained by Nevil Hopley with an enormous amount of resources and activities for TI-Nspire (and more!).
- Mathforum.org: a very rich site featuring problems, activities and a weekly newsletter regarding the use of technology in Maths teaching.
- Øystein Nordvik's webpage: don't let the name scare you, this page is in English. And it has some amazing constructions for the TI-Nspire computer software (making heavy use of color and the bigger resolution of the computer).
This page is a work in progress. Anytime I find out a new web site worth mentioning I'll add it to this list.
