Detailed Activities

Reading and Highlighting Key Details

  1. Read the selected informational text aloud with your child, or have them read it independently if they are able.
  2. Explain what key details are and how they help us understand the main idea.
  3. Have your child highlight or underline important facts or details in the text.
  4. Discuss together why these details are important.
Answering Questions About the Text

  1. Provide your child with a worksheet containing questions about the text.
  2. Encourage them to find answers by referring back to the key details they highlighted.
  3. Review the answers together and talk about how the details support the main idea.

Parent & Instructor Notes

  • This lesson focuses on helping your child learn to find important information in non-fiction reading, which is a key skill for understanding texts.
  • You don’t need to be an expert in the topic; your role is to guide your child in noticing details and thinking about why they matter.
  • Encourage your child to ask questions about the text and explain their thinking to build deeper comprehension.

Assessment Questions

  • What is the main idea of the text?
  • Can you name two key details that support the main idea?
  • Why do you think these details are important?

Extension Ideas

  • Have your child write a short summary of the text using the key details they identified.
  • Explore another informational text on a different topic and repeat the activity to build confidence.
  • Create a simple graphic organizer together to list the main idea and supporting details.

Frequently Asked Questions

Try reading the text together slowly and ask guiding questions like ‘What is this part telling us?’ or ‘Why do you think this detail is important?’. You can also model highlighting key details yourself.

Look for short texts with clear facts and simple language appropriate for a 4th grader. Topics that interest your child, like animals or weather, can make the reading more engaging.

Teacher’s Guide

Common Misconceptions:

  • Students may confuse key details with minor or unrelated information.
  • Some students might focus only on the main idea and overlook supporting details.
  • Students may think all sentences are equally important.

Scaffolding Ideas:

For Struggling Students:

  • Use shorter texts with fewer details to identify.
  • Provide a list of possible key details and have them choose which ones are important.
  • Read the text aloud and discuss it together before highlighting.
For Advanced Students:

  • Have them find key details and explain how they connect to the main idea.
  • Ask them to compare key details from two different texts on the same topic.
  • Encourage writing a detailed summary or creating a presentation about the text.

Pacing Recommendations:

  • Spend the first 15 minutes reading and discussing the text and key details.
  • Use 20 minutes for the highlighting activity and guided questions.
  • Reserve the last 10 minutes for review and discussion to ensure understanding.

Standards

  • 4.RI.5 — Explain the overall structure of events, ideas, concepts, or information in a text or part of a text.
