How I Use It
I use this to show the different representations of a math problem. For example, some problems have a geometric and algebraic representation. With the emphasis on integrating math disciplines in Common Core, Wolfram Alpha can reach a broader range of thinkers.
With respect to problem solving, it would be great if the web site offered a way to show the work without users paying for the Pro service while at school. It does a great job with in-depth explanations instead of just getting answers. However, it provides a wonderful opportunity for extended learning. For an example of extended learning, the students can discover how the program comes up with certain properties of shapes.
