Do your students struggle with figuring out the main idea? Elementary teachers through fifth grade are always trying to come up with activities to help their students with this skill.
Sometimes main ideas are easy to identify—and sometimes they are much more difficult. However, if your students have a good foundation with what a main idea really is, they will be more likely to have success.
Today, I am outlining a step-by-step scaffolded approach to teaching your students about main idea, starting with identifying a topic.
NOTE: While some of these ideas may seem too “little” for your grade level, they really can help build up their foundation. Give them a try!
1. Identifying the Topic
In this activity, students are given a bag with six images to study.
The images are all related in some way. Students will identify the topic of the bag. (Ex: seaweed, water, octopus, shark, whale, coral, topic: ocean)
When looking at one picture alone it may be hard to identify the topic, but when the images are together, students can figure it out.
How to Differentiate Identifying the Topic
- Give younger students topic cards to match the pictures to
- Give older students real-life photographs to study
2. Understanding How Words are Related
Similar to the previous activity, students will look at a group of words to determine how they are related.
Now, you may feel that this is the same activity as the previous one, but it really isn’t. By having students look at the words, they start to think about how words in a text are connected. (This will help them later when they have to figure out how details support the main idea.)
How to Differentiate Understanding How Words are Related
- Give younger students simple words that they have interacted with before (leaf, pumpkin, scarf)
- Give older students higher-order vocabulary to relate (solid, liquid, gas)
3. Understanding How Sentences are Related
In this activity, students are provided three detail sentences and have to determine how they are related. This gets students thinking like an author, (which prepares them for the next levels).
The reason this helps:
Instead of simply handing students a paragraph and asking them what the topic or main idea is, this activity has students start by looking at the actual words in the sentences. What words are repeated? How are those words related to each other? (Like our previous activity taught them to think about!) What does the author seem to be describing or telling me about?
This activity allows them to think like a writer. They can ask themselves, what would I write as the main idea of this paragraph?
Then, when it is time for them to search a paragraph for a main idea, they are already familiar with thinking like an author!
4. Writing a Main Idea and Details Paragraph
In this activity, students are provided various facts about a topic and are asked to construct a main idea and details paragraph.
Once again, students are thinking like a writer. How do the facts relate to each other? What would my main idea be?
How to Differentiate Writing a Main Idea and Details Paragraph
- Give younger students a simple graphic organizer to fill in if they have not been taught paragraph structure yet
- Give older students facts related to science/social studies topics you are studying
5. Reading to Identify the Main Idea
In this activity, students are given mixed-up sentences from a paragraph and must identify which one is the main idea and which ones are the details.
This higher-order-thinking skill forces them to look at the actual content of the sentences, think about how they are related, and determine which sentence ties them all together.
Students begin to develop a deeper understanding of how main ideas and details are related to each other.

6. Explaining How Details Support
After students have identified which sentence from the paragraph is the main idea, it’s time for them to justify their answer.
Students will explain how they know the details support the main idea. This takes the activity from simply identifying the main idea, to defending how you know that was the main idea.
I hope these activities help you support your students through their understanding of topic and main idea and details.
