Blog #3: Questions

A few questions that I have: I think CGI is a really great addition to mathematics but, I feel like it's only appropriate for lower elementary. My question is, how would you use CGI in upper elementary, or even middle school mathematics? Can you? Another question I have deals with the syllabus. It talks about "wikispace," which is something I am VERY unfamiliar with so...what is it? Also, aside from online manipulatives, which we already have looked at, what are some other pertinent technologies that should be incorporated into a math class?
