Dear Third-Grade Families,
We’re beginning a reading skill that helps students understand informational texts—books and articles that teach us about real people, places, animals, or ideas. As we read, students will learn to identify what a text is mostly communicating and how its important details help explain that idea.
What does this mean in kid-friendly terms?
Students will figure out the text’s big message, find the important information that helps explain it, and tell that information accurately in their own words.
The three parts of the learning
Find the main idea: What important idea does the author communicate about the topic?
Recount key details: Tell the important information from the text accurately and explain how it connects to the main idea.
Paraphrase key details: Restate important information in your own words without changing its meaning.
Topic vs. main idea
The topic is the general subject. The main idea says what the author wants readers to understand about that subject.
● Topic: “The text is about beavers.”
● Main idea: “Beavers use trees, branches, mud, and other materials to build dams that change their surroundings.”
The second statement tells more than the subject: it explains what the text communicates about beavers.
What makes a detail “key”?
A key detail is important information that helps explain or develop the main idea. It might be a fact, example, or description. Not every interesting detail is a key detail; students consider whether it helps a reader understand the text’s big idea.
For example, “Beavers pile branches across moving water” is a key detail because it shows one way beavers build dams.
What does it mean to paraphrase?
To paraphrase is to understand an idea and explain it in your own words while keeping its meaning accurate. It is not just swapping a few words for synonyms, copying the sentence, or adding information from outside the text.
In Shark Lady: The True Story of How Eugenie Clark Became the Ocean’s Most Fearless Scientist, the text says Eugenie collected hundreds of fish in the Red Sea, including three species that had not been discovered before. A paraphrase could be: Eugenie collected many fish in the Red Sea and found three fish that scientists had not seen before. It uses different wording but keeps the key information.
Questions to ask at home
● What is this text mostly about, and what does the author want you to understand?
● Which details helped you figure out the main idea?
● How does that detail support the main idea?
● Can you tell me that detail in your own words?
● Is there an interesting detail that isn’t essential to the big idea?
Simple ways to support learning at home
● After reading a nonfiction book, invite your child to describe its big idea in one sentence.
● Ask your child to point to or recall a detail that supports that idea.
● Take turns explaining a detail in your own words, then check that its meaning stayed the same.
● Encourage your child to look back at the text when unsure. The text’s details help readers make a strong, accurate explanation.
