Geometry explorer, worth downloading. Geared towards geometry constructions more so than Geogebra.

"In this article we introduce the free educational mathematics software GeoGebra. This open source tool extends concepts of dynamic geometry to the fields of algebra and calculus. You can use GeoGebra both as a teaching tool and to create interactive web pages for students from middle school up to college level. Specifically designed for educational purposes, GeoGebra can help you to foster experimental, problem-oriented and discovery learning of mathematics. We will illustrate the basic ideas of the software and some of its versatile possibilities by discussing several interactive examples."

How to develop a circle equation in algebraic form when the circle touches the horizontal x-axis and learn how algebra is used in geometry to derive the equation of a circle in algebraic form in mathematics.

Math applets from Edinformatics. 

Activities from TI. Well designed and include multiple representations, technology and exploration

Some nice online resources that might be useful in your classroom. I haven't investigated them all as of yet, but will be looking into them to make more specific recommendations. 

Mathematics and Multimedia GeoGebra Step-by-Step Tutorial SeriesThe objective of the GeoGebra Step-by-Step Tutorial Series is not only to teach the readers how to use the software, but also to suggest how to use GeoGebra in teaching and learning mathematics. Most of the tutorials are (or will be) linked to related articles containing explanations and proofs about the mathematics discussed in the tutorials.

he YAY MATH video project is a free service dedicated to meeting the growing need for math success in a POSITIVE, LIVELY, and CONFIDENCE BOOSTING way. YAY MATH stands as the only online video lesson series filmed in a live classroom, with real student interaction. Since its inception two years ago, and over a million YouTube views since, gone are the days of the "I just can't do math" style of thinking. It's time to evolve. It's time to re-invent our entire approach to success.

Great activity for having students develop their skills at estimating. Potential for developing their understanding of error analysis/estimating/measurement. Easy to play, and allows comparison to other players or comparison to their own plays.

Simple tool, but easy to use and nice for building some quick examples using the IWB. There are other ways of doing it using Smartboard software, but kids can use this tool, create some examples, do screen captures, and share with each other or in docs.

Choose a cross section, then click on the points that lie on the edges of the cube to try and create the cross section. press Create to see what cross section you made, and if you want, you can rotate the cube to take a look at it. It will give you feed

A collection of 279 Math Applets designed by International Education Software. Apps show individual concepts from multiple perspectives, usually conceptually from a diagram and graphically. Not very dynamic in that students wouldn't be able to manipulate multiple variables, but great to use with an interactive white board to show connections between representations and to confirm calculations/predictions.
