I am currently the Library Aide for my campus, our campus does have a mobile computer lab.
Kid Pix Deluxe has so many sites to choose from, I found it hard to navigate and choose.
Wordle: Our Library already uses
Wordle for the Bluebonnet project that the kids do. The Kids really enjoyed doing this it helps with their vocabulary skills, word association, story comprehension by using key words.
TerraClues: seems a little advanced for our campus,
possibly 4th grade, I had fun searching the clues but, at times I got lost or confused as to what I was looking for as the clues got harder.
