Main Idea
What is the “Main Idea”?
The main idea is what the text is about and what the author wants you, the reader, to know. If
someone were to ask you, “What was that book or article about?” they are asking you about the
main idea. When you can tell them exactly what it is about, you have grasped the main idea.
What is the purpose of the main idea?
The purpose of the main idea is two-fold. First, it lets the reader know what the text is about so
that the reader can decide whether or not to continue reading. Secondly, its purpose is to engage
the reader quickly. It serves to capture and take hold of the reader within the first minute or two
of picking up the text.
How can you identify the main idea?
The main idea is usually (but not always) apparent within the first two to three sentences. Often,
the main idea is the same as the topic sentence. At other times, the title may state the main idea.
After the first two or three paragraphs of a text, a reader should be able to identify the main idea
and what the text is seeking to do. Some questions you can ask yourself after these first
paragraphs include:
● Does this book/article/text tell me who, what, when, where, or how about something?
● Does this piece’s title tell me what I am reading?
● What is the point of this text?
Main idea and supporting details
The text you are reading will have additional details that help support or lend credence to the
main idea. As you are reading, it is important to stop periodically to decide reflect how the
supporting details help illustrate the main idea and to determine how they relate to each other.
Rereading and reviewing
Sometimes it is necessary to read the text again to decipher the main idea and the supporting
details. Read each paragraph carefully and consider why the author is sharing this information.
Example: Glass is such a popular material in our homes because it has all kinds of really useful
properties. Apart from being transparent, it's inexpensive to make, easy to shape when it's
molten, reasonably resistant to heat when it's set, chemically inert (so a glass jar doesn't react
with the things you put inside it), and it can be recycled many number of times.
