The framework of the 6 + 1 Traits Writing Model identifies six qualities of good writing.

#1 Ideas covers the main message in a piece of writing. Ideas are the content of the writing piece. They are the “heart and soul” of good writing. It is important for students to remain focused on the writing by selecting the idea or topic, remaining focused on the idea, elaborating on the idea, and using details and information to further develop the piece of writing. Ideas enable students to move from a general to more specific writing. 

A good idea is clear, interesting, and original. It makes the reader say, "Wow!" or "I never would have thought of that!" Without good ideas, your writing would not have much of a point. Your reader would be bored!
