Mathematics 24x7

There is no escape...believe it or not. Mathematics is everywhere.

Web is expanding daily with lots 'n' lots of tools and softwares. Are you using any free Math software? Please share about it here.
Thanks

My favourite is Geogebra (the free version of Geomters sketchpad) http://www.geogebra.org/
Hi, Maggie
GeoGebra is my favourite too. In our school we have prepared around 50 interactive lessons using this software. I have uploaded some lessons on GeoGebra Wiki.

Keep Sharing.
Children love to explore graphs using this tool. In a class it is not feasible to analyse more number of graphs manually. But using this tool , the graph appears on the screen on a mouse click and children analyse change in graphs by changing values.

Here are a few free software programs:
R - statistical program --> link
SAGE - symbolic math environment --> link
Formulator Tarsia - equation editor & jigsaw activity creator --> link
Green Globs - Not actually free, but two activities. First game is points on a graph and students must use fewest equations to pass through all point. Second is game relating real world actions to graphs. Tracker looks interesting, but I have not tried it. link
Mathtrax - interesting graph tool suggested by a member of my PLN, although I have not had a chance to try it --> link

Note: many other tools at my Delicious account --> link

Some of my currents:
(1) I am exploring the use of MIT's Scratch as programming tool to model math (and TurtleArt as low-end intro to geometry)
(2) Grad work involves creating a collaborative and visual math environment where students discover numeric literacy and problem solving skills.
Several new links for me here and I'm sure I'll find many more in your delicious account. Would be very interested in hearing more about your graduate work. I'm also looking carefully at Scratch for use in teaching math. Been using Logo for years.

The Graph software is so easy to use. I give it to my students to create graphs for their projects. The graphs look very professional. It's easy to change intervals on the axis and for my trig classes I can have the x-axis in intervals of pi. Great tool.

Geogebra and Formulator Tarsia would certainly be on my list. My other favourite is D.R.A.P.E. (Drawing And Programming Environment), which is a visual logo program which is great for kids to explore and learn angle properties in polygons. It was formerly freeware by Mark Overmars but proved so popular that it is now sold commercially by Sherston Publishing Group in a combined package called "Prof. Roberts ICT Problem Solving Kit".

Try this one. It is very interesting.
Thanks for sharing these. I've been on a bookmarking frenzy since joining this site!

SMath studio Absolutely free mathematical application with "paper"-like interface and numerous computing features .

Download
How about http://www.standards.dfes.gov.uk/primaryframeworks/library/Mathemat... for elementary teachers. They are downloadable or run from the net flash animations for elementary classes.

I also use www.quizlet.com for review of math terms.

For demonstrating steps on a graphing calculator I use a free Virtual TI found at http://www.ticalc.org/archives/files/fileinfo/84/8442.html

I also use a screen capture program to put the answers to the homework assignment into Powerpoint. It can be found at
