    A couple of students in my on-line classes have been asking questions about multiplying fractions.  Should you simplify before or after multiplying?  How should you simplify?  By cross-canceling directly, or by a prime factorization and cross-canceling combo?  Here are some videos I have made to help clarify the situation. http://content.screencast.com/users/Mallwalker52/folders/Jing/media/595b65da-573a-4dfd-92c3-2416f129b1f5/jingswfplayer.swf View on screencast.com » http://content.screencast.com/users/Mallwalker52/folders/Jing/media/6637f493-b715-43a6-8400-fa4e3be154c1/jingswfplayer.swf View…

    I just started facilitating my first on-line course ever this week.  I say facilitate, because I really don't believe that I'm actually teaching the students anything in the traditional sense.  In fact, they are actually learning through reading the textbook, discussion forums on ANGEL, and MathZone.  However, since this is my first experience with MathZone,…
