WolframAlpha now has a dedicated page (and sub-pages) on this blog to make resources easy to find.
You will find this series on the Use of Technology menu.
Check Fred Feldon’s presentation on Slideshare which discusses the implications of WolframAlpha for Mathematics education and also includes many examples.
My students increasingly use this Guillermo. I think WolframAlpha has many fans!
Thank you Colleen for sharing. I am a big fan of Wolfram Alpha
