Main Idea and Supporting Details
Main Idea and Supporting Details
Main Idea -
The most important idea about a topic that a particular text or paragraph conveys.
Supporting Details –
Words, phrases, or sentences that tell more about the main idea.
Remember the Main Idea House?
A paragraph is a group of sentences related to one main idea.The main idea is like the roof of a house.The roof of the house is made up of two parts: the word or phrase that the paragraph discusses; the message (what the author wants you to know about that word or phrase).
Create a main idea house for the three paragraphs on page R8.
Don’t forget that the roof must be supported (proven, exemplified, described, etc.) with supporting details.

happen.

Chronological Order
Look for words and phrases that identify times, such as “in a year,” “three hours earlier,” “in 202 B.C.,” or “the next day.”
