• The Froggy Page
  This is the URL for the first homepage I visited when I began to surf the net. I still love it because I love frogs. Even though I have not used it in my classes, I have used it as a launch site to discover information which I have shared with my students. I have also suggested they visit the site when they are researching amphibians. Besides, it's just FUN!
