A good lesson can be built around a prefix or a root of a word.  

For example:  The teacher explains and writes on the board that "vid" and "vis" are from the Latin and mean to see.  

Then the teacher can draw "vid" and "vis" words from the class, third grade through adult.  Members of the class become very involved and shout out the words that they know.  

Together the teacher and the class write the words in syllables: the teacher on the board, the students on their papers.
