If you enjoy word clouds like Wordle or Tagxedo then you will enjoy the app Word Collage! Word Collage is a great app to create word clouds.
The children can copy and paste text they have found to help highlight key information.
They can also type in their own word to create beautiful images of their own writing.
Once they are done their Word Collage can be saved to the iPad Photo Album or emailed to you and/or their families.
