The URL's I have collected as links to great sites for 9-12 Mathematics are not for my use only. I have them bookmarked on all of the computers my students will be using in a bookmark file called Ms. Savell's MAth Links. This way if I want to incorporate these sites into any of my lessons, I do not have to wait for the students to type in the URL. They can simply go to the bookmarked site. This also give the students places to start when they need to search for math topics. I encourage all of my students to add bookmark to any relevant sites they find on their own.
