I decided to go with Delicious to manage my bookmarks. Two new websites that I found while searching Delicious are a math dictionary and Story Jumper. I used the tags math and literacy to find them.
I think that social bookmarking will be useful teacher to teacher as well as teacher to student and teacher to parent! I have struggled in the past with getting kids to the really cool website that I found for them. I think that this social bookmarking will get them to the correct website without having to write the address on the white board and then wait for the students to type it in! I haven't explored sharing bookmarks yet, but I'm sure it will be a great way to share with kids, fellow teachers and parents!
