Looking for
   repeated
 words and

good way to
 find topics.
Can you find the topic?
Colonial Williamsburg is a great place to
visit. In Williamsburg, you can see how
people lived in colonial times. There are
guides in costumes who can show you to
taverns, shops, and houses. You can even
sample some colonial food at the restored
taverns! One visit to Williamsburg will
make you feel as if you have been
transported to the 1700s.

The topic was Williamsburg

We could tell
this because
  the word
Williamsburg
was repeated
several times
But some paragraphs are tricky

Sometimes,
authors use
  different
words for the
 same thing

Can you find the multiple referents?

The topic is still Williamsburg, even though the word is only
stated once.
What is the topic of this paragraph?

Assateague Island is a very special place.
A long sandy beach stretches into the
Atlantic Ocean. Windswept dunes are
home to foxes and seagulls. The famous
wild horses, or ponies, also live on this

  have found
  the topic of

  we can find
the main idea.

Where is the main idea?

  In many
paragraphs,
   the first
 sentence
 states the
 main idea.
When the author states the main idea, it is called an
explicit main idea.
Where is the main idea?

But the main
 idea is not
always in the
     first
  sentence.
Look for the explicit main idea

 Croak, croak, kerplop! What’s that at the water’s edge?
 It might be a green frog, a creature that’s well-suited
 for life at the pond’s edge. Green frogs like to live
 where the land meets the water. This keeps them safe
 from predators that live on the land. When a predator
 like a snake comes near, the green frog can quickly leap
 into the water and get away. Green frogs can eat
 animals from both places, including crayfish, spiders,
 fish, and even birds.
Look for the explicit main idea
The first sentence is
not the main idea.

        places, including crayfish, spiders, fish, and even
        birds.
What about the second
              sentence?
Main ideas are not
usually expressed as
questions


         Croak, croak, kerplop! What’s that at the water’s
         edge? It might be a green frog, a creature that’s

         frog can quickly leap into the water and get away.
         Green frogs can eat animals from both places,
         including crayfish, spiders, fish, and even birds.
What about the third sentence?

This sentence
includes the
topic
           Croak, croak, kerplop! What’s that at the water’s
         edge?It might be a green frog, a creature that’s well-
         suited for life at the pond’s edge. Green frogs like to
         live where the land meets the water. This keeps
         them safe from predators that live on the land.
                                        It also makes a

         frog can quickly leap into the water and get away.
         Green frogs can eat animals about the topic
                                        from both places,
         including crayfish, spiders, fish, and even birds.
This is called the topic sentence
        It’s kind of silly that the sentence that states the
        main idea is called the topic sentence, but that’s just
        the way it is.
    Croak, croak, kerplop! What’s that at the water’s

Finding the main idea
To find the main
idea, figure out
 the topic first.
Then, look for a
 sentence that
 states a main
point about the
      topic.

between a

A main idea includes the topic

 An implicit main idea is

Does every paragraph work like
            this?
A. Yes! Every paragraph in the whole
   universe is like this and you will
   never have to think hard again
B. No, some paragraphs are different.
   Sometimes the paragraph has the
   topic sentence at the end of the
   paragraph. Sometimes the main
   idea is very hard to find.
Does every paragraph work like
              this?
• The answer, of course, is B
• Some paragraphs do not follow
  this structure because the
  author wants to make the
  reader think more carefully
• And sometimes the paragraphs
  are just poorly written!
These guidelines usually work
 1. Find the topic of the paragraph
 2. See if the first sentence states the main
    idea
 3. If not, check other sentences in the
    paragraph
 4. Find the sentence that includes the topic
    and states a main point about the topic
 5. Make sure that the other sentences in the
    paragraph relate back to the main idea
