Finding Topics and Main Ideas

Tools for reading nonfiction

Finding Topics
  • To understand a paragraph, it’s important to find the topic
  • The topic is the idea to which all of the details in the paragraph refer
  • A topic is usually expressed as a word or phrase
can you find the topic
Can you find the topic?

Water is an amazing resource. Everyone in the world depends upon it. Every creature needs water to survive. Without water, we would not last long. Water makes our world beautiful.

Water is an amazing resource. Everyone in the world depends upon it. Every creature needs water to survive. Without water, we would not last long. Water makes our world beautiful.

Topic = WATER

slide5
We could see that the topic was water because it was repeated again and again
  • This is a good way to help us find a topic—looking for repeated words or phrases

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.

We could tell that the topic of the paragraph is Williamsburg because it was repeated several times
finding the topic
Finding the topic
  • The topic of a paragraph is not always repeated over and over in the same way
  • Sometimes, you need to look for multiple referents—that is, words or phrases that refer to the same thing
looking for multiple referents
Looking for multiple referents

Here is the Williamsburg paragraph again. Notice how Williamsburg can be replaced by other words or phrases:

Colonial Williamsburg is a great place to visit. In this Virginia town, 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 this place will make you feel as if you have been transported to the 1700s.

slide11
Williamsburg is referred to in several different ways
  • This Virginia town and this place both refer back to Williamsburg
  • The topic is still Williamsburg
look for the topic in this paragraph
Look for the topic in 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 small island.

look for the topic in this paragraph1
Look for the topic in 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 small island.

did you figure out the topic
Did you figure out the topic?
  • Authors sometimes refer to the same idea in different ways
  • “Assateague Island” and “this small island” are really the same place
  • When you are trying to figure out a topic, look for different ways of saying the same thing
using topics to find main ideas
Using topics to find main ideas
  • Once we have figured out the topic of a paragraph, we need to find the main idea
  • The main idea is the main point of the paragraph

MAIN IDEA = Topic + a statement about the topic

can you find the main idea
Can you find the main idea?

Water is an amazing resource. Everyone in the world depends upon it. Every creature needs water to survive. Without water, we would not last long. Water makes our world beautiful.

did you find the main idea
Did you find the main idea?
  • The first sentence is the main idea
  • Water is an amazing resource
  • The topic = water
  • The main point about the topic = it’s an amazing resource

did you find the main idea1
Did you find the main idea?
  • Once again, the main idea was in the first sentence
  • Topic = Williamsburg
  • Main point about the topic= it’s a great place to visit
is the first sentence always the main idea
Is the first sentence always the main idea?
  • What do you think? Talk about it with your partner!
think about this paragraph
Think about this paragraph

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.

is the first sentence the main idea
Is the first sentence the main idea?

that doesn t make sense
That doesn’t make sense!
  • Croak, croak, kerplop! can’t be the main idea of the paragraph
  • This sentence does not express a topic or a main point about the topic
let s find the topic first
Let’s find the topic first

let s look at the second sentence
Let’s look at the second sentence

Green frogs can eat animals from both places, including crayfish, spiders, fish, and even birds.

is it the main idea
Is it the main idea?
  • Do you think that the second sentence, What’s that at the water’s edge? is the main idea?
  • This doesn’t make sense either. The paragraph is not mostly about the water’s edge
what about the third sentence
What about the third sentence?

is it the main idea1
Is it the main idea?
  • Is the third sentence, It might be a green frog, a creature that’s well-suited for life at the pond’s edge the main idea?
  • This sentence includes the TOPIC (green frog) and a main point about the topic (it’s well-suited for life at the pond’s edge)
hooray the main idea
Hooray! The main idea!
  • As you can see, the first sentence is not always the main idea
  • To find the main idea, you need to think about the topic of the paragraph
  • Look at each sentence until you find the best main idea sentence
now try this one4
Now try this one

What a gorgeous view! Kings Gap State Park is a great place to see the Cumberland Valley. This is because the park was built on top of a mountain. From the mountain top, the fields and farms of the valley stretch out far below. The Doubling Gap, a mountain that curves like the letter s, can also be seen.

how do we find the main idea
How do we find the main idea?
  • Start by finding the topic
  • Then look at each sentence in the paragraph
  • Look for the sentence that states the topic and gives a main point about the topic
  • Once you think you have found it, match it against the rest of the sentences

  • The topic, then, is Kings Gap State Park
  • To find the main idea, we need to understand what the paragraph is saying about Kings Gap State Park
let s try the first sentence
Let’s try the first sentence

better
Better!
  • The second sentence, Kings Gap State Park is a great place to see the Cumberland Valley, includes both a topic and a main idea
  • Let’s see if all of the other sentences in the paragraph relate back to it
do the rest of the sentences relate
Do the rest of the sentences relate?

From the mountain top, the fields and farms of the valley stretch out far below. The Doubling Gap, a mountain that curves like the letter s, can also be seen.

The rest of the sentences do relate back to the second sentence. It’s the main idea.

  • What is the topic of a text?

The topic is the word or phrase that all of the sentences in a paragraph refer to

The main idea of a paragraph is the topic, plus a feeling or attitude about the topic

what have we learned1
What have we learned?
  • Is the main idea of a paragraph always the first sentence?

No! Sometimes the main idea appears in other parts of the paragraph

  • How do we find the main idea?

We need to think about the topic, and look for a sentence that includes the topic plus a main point about the topic

does every paragraph work like this
Does every paragraph work like this?
  • Yes! Every paragraph in the whole universe is like this and you will never have to think hard again
  • No, some paragraphs are different. Sometimes the paragraph has the topic sentence at the end of the paragraph. Sometimes the author leaves out the main idea altogether, and we need to figure it out
and the answer is
And the answer is…
  • The answer, of course, is B
  • While most paragraphs do have a stated main idea, some do not
  • Sometimes this is because the author wants to make the reader think more carefully
  • (Dark secret) Sometimes it’s because the author just didn’t write the paragraph very well!
but these guidelines usually do work
But these guidelines usually do work
  • Find the topic of the paragraph
  • See if the first sentence states the main idea
  • If not, check other sentences in the paragraph
  • Find the sentence that includes the topic and states a main point about the topic
  • Make sure that the other sentences in the paragraph relate back to the main idea
