If you are looking for tips on teaching main idea and key details in upper grades, you’re in the right place! This blog post is for all of you 4th and 5th grade teachers who are getting ready to teach main idea in informational text.
- 4th Grade RI: Determine the main idea of a text and explain how it is supported by key details; summarize the text.
- 5th Grade RI: Determine two or more main ideas of a text and explain how they are supported by key details; summarize the text.
Introduce Main Idea and Key Details with Anchor Charts:

Main idea is a skill that can give students some trouble. You may introduce the skill in seclusion and work toward mastery, but I also suggest revisiting the skill throughout the year.
When introducing main idea, an anchor chart is a good place to start. Students need to understand the purpose and parameters of main idea. An anchor chart needs to have a clear description of the topic or skill. So, you can create (or print/display) an anchor chart and revisit it throughout your unit. The anchor charts below can be printed or displayed digitally. Then, as you revisit main idea throughout the year, pull the anchor chart back out to reinforcement.
Modeling with Mentor Texts

Another essential component to teaching main idea in upper grades is modeling. There are so many high-quality informational texts out there! For main idea, I like to choose texts that have a straight-forward message. These texts may be shorter/simpler than a typical intermediate mentor text. But, they will provide you with the information students need to properly learn main idea skills.

Lesson Additions

Don’t forget about adding informational videos and activities, like BrainPop! Tim and Moby make the idea of main idea easier to understand for students with great visual elements and explanations. There are graphic organizers and quizzes that your kids can use, too!

Focusing On Key Details

Your next step will be working with key details. It is important for students to be able to differentiate details. This activity requires students to match details with specific main ideas. This will help students learn how to determine which details are important. It will also help them with understanding what kind of details support a main idea.
What about Multiple Main Ideas?

In 5th grade, students will be identifying multiple main ideas. For this, students will be looking for sections of information that are about a similar topic. Texts are longer and more detailed in 4th and 5th grade, so the information will be divided into sections. So, students will need to learn how to identify the main ideas of these subsections of text. Then, they will be able to figure out what the entire test is about.
Use Graphic Organizers & Mentor Texts

Using mentor texts is a powerful way to teach main idea and key details. Letting your students use your mentor texts to reread AFTER you’ve used it within your lesson is powerful! Mentor texts also make lessons more engaging and relatable for upper elementary learners.
Provide Reading Passages for Practice

Reading passages give students authentic opportunities to practice identifying main idea and key details. Use markers to highlight evidence and answer comprehension questions.
