Sentence Diagramming

My students are having difficulties recognizing whole sentences, so I taught them how to diagram.

These are the best diagramming site links I've found:
http://www.geocities.com/gene_moutoux/diagrams.htm
(and my favorite sentence here: http://www.geocities.com/gene_moutoux/dialit9.htm)
http://www.lifestreamcenter.net/DrB/Lessons/TS/diagram.htm
(this site is very basic)
http://grammar.ccc.commnet.edu/GRAMMAR/diagrams2/diagrams_frames.htm
(this one requires that you understand parts of speech and grammatical terminology)
http://www.slate.com/id/2201158/
(too political for classroom use, but quite amusing)

(and this is where you order the software that will do it for you - cheaters!)
