I think this is a GREAT resource with massive potential. If you teach any current issues/sociology/modern history courses then this tool is a must. Even if you teach courses like 'algebra' then this tool has potential. I spent less than five minutes looking at the query 'regression analysis' and found two valid content related applications of regression analysis that I could easily use with an algebra I, II or precal course. As an example in the first resource I came across this http://web.sny.tv/news/article.jsp?ymd=20090424&content_id=1499716&vkey=1 article from SNY.tv that mentions "each (interception) in the minus column costs you approximately six points on average over many years of regression analysis." I can see just having an algebra I course examine/explain what that means mathematically, I can see allowing some students to group, decide what data they would need to confirm that analysis and if you wanted let them analyze the data or look for the analysis that has already been done by contacting the author/NFL. If I can find that kind of information within 5 minutes then imagine what someone with imagination could do! Great resource, a must share with your core content teachers and I firmly believe this tool could quickly vault up the list of most useful very ,very quickly. I can't let this go without thinking about differentiation in the classroom, I search for a topic, let groups look at the timeline and choose their own reading (if I have a group that will be challenged by their choice, I might point them to another reading that might scaffold their understanding), but I've built in choice, built in the ability to manage the sources, opened up the ability to quickly find multiple types of sources (video, blogs, primary sources).

The single best online algebra tiles applet available.

Creating Connections: Promoting Algebraic Thinking with Concrete Models

Creating Connections: Promoting Algebraic Thinking with Concrete Models - the article elaborates on the use of concrete models to teach polynomial topics.

Modumath as linked from Wisconsin Online learning resources. Interesting videos of algebra concepts, not a huge library but well worth the exploration. You must join http://www.wisc-online.com/ to gain access, but it's free and very interesting.

A simulation of the stock market. A great running application to use in algebra classes, as it allows students to use algebraic concepts to manage their portfolio. Not directly skill or concept related, but can utilize graphing, formula use (as simple as P/E ratio, to regression analysis, to derivatives). For those teachers who think a little outside the box. I would be glad to hear how others might envision using this in their classroom.

Get the Math is a multimedia project about algebra in the real world. See how professionals working in fashion, videogame design, and music production use algebraic thinking. Then take on interactive challenges related to those careers.

Really interesting way of doing a multimedia search. Not sure it's classroom safe, even with safe search on there were several images that were beyond borderline. When I did compound search "algebra" + "linear" much tighter and deleted virtually all inappropriate material. I just like the way you can explore the information. If you have students gathering information and tagging with specific tags like "wjhsconlit09" then you could pull up all of that material without interference. I think it's a great tool for that kind of exploration.

Karl's approach to homework with his algebra I students. Flipping the process, examples from a video at night followed by discussion and practice during class. 

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.

This is a compilation of Karl's Transparent Algebra posts. He does such an incredible job of making his thinking visible for all of us in how he is planning his course for the upcoming year. I share it because I think it's a valuable example of a reflective practitioner and worth sharing. If you have any teachers who might benefit from reading some of his reasoning, I encourage you to send them to his blog!

Lots of different 'games' to play to reinforce vocabulary for all kinds of subjects. If a student/teacher just wants to create a list of study cards this can do it. If there is a station in your class for vocabulary development you can use this site in lots of different ways to have students practice vocabulary skills. I dare you to try the space race. It's tough!

"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."

Interesting way to approach analysis of slope relationships. 

Virtual Nerd is developing a nicely organized site. The videos are primarily symbolic in nature but are thorough, organized, and do a nice job of modeling notes to accompany the explanations. 

From Glencoe, some IWB looking mathematics manipulatives including color counters, algebra tiles, protractors, ruler, etc. that can be manipulated either on the computer of on the IWB screen.

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.

Having students start understanding number properties early is a significant aspect of developing algebraic reasoning. I really like that this game allows students to 'play'/explore different number combinations. I can even see using this game with older (3-5th) students to have them explore different characteristics of the problems, i.e. 3 + 4 = 7 the larger number goes at the end, 3 and 4 can be switched and still get 7 to introduce number properties in a concrete experiential way.

Making connections to prior knowledge to assist in the learning of math concepts - using number lines, various examples provided.

Great connections between math and "real world" settings. Well developed use of multiple representations.
