Try Madlibber.com! Students are given a list of words that they must choose (adj, verbs, nouns, adverbs, etc.), and then they get to see the story that they created. BUT, it doesn't end there! Students can also create their own stories for others to complete. This makes it more adaptable to all subject areas. Students could create a math or history story, leaving blanks for different vocabulary terms.
