Material Generator Tools

It is quite difficult to choose only three material generator tools.....  My students have used Microsoft Publisher to create brochures for field trips when we researched famous landmarks in Alabama.  The kids were "travel agents" and developed a trip that included a detailed brochure of one of Alabama's landmarks, an itenerary, and the projected cost of the trip.  I have considered but have not taken on allowing collaborative groups to develop a web page on topics covered in science/social studies. Many of the web page design software tools are not user friendly, so I have put this project on hold.  I use rubrics to grade, and would really like for the students to try one of the rubric generators to create their own rubrics.  I feel like this would really develop ownership of the project at hand, and they are often more critical than I am.
