Central Idea

A central idea can also be called a main idea.
It is not just a topic or subject.
It will name the topic and make a statement about that topic.
A central idea will be a complete sentence.
It will be a declarative sentence, never a question.
It will be specific to the text.
    It will not be a theme. = It will not be a universal message.

Examples and Non-Examples: 
Examples:  
Jim Thorpe may have been the greatest athlete of all time. 
Jim Thorpe was an outstanding athlete in many sports.

Non-Examples
Jim Thorpe            [This is just a topic. A central idea will be a complete sentence.]
The greatness of Jim Thorpe    [This is just a topic. A central idea will be a complete sentence.]
This paragraph tells about what a great athlete Jim Thorpe was.   [This is just another way of stating the topic.]
A person can excel in many ways.  [This is a theme.  It is not specific to Jim Thorpe.]

Each supporting detail needs to provide support or explanation for the central idea.


With Central Idea, we call the sub-ideas and evidence supporting details.
