Lesson 2: Distinguishing Main and Secondary Details

Lesson Plan

Learning Goal
Distinguish main details from secondary details in a paragraph.
Duration
Approximately 50 minutes
Necessary Materials
Provided: Direct Teaching and Guided Practice Passage,“Are You Smarter Than a Fifth Grader?;”Independent Practice Passage, “Seven Great Summits” and Worksheet
Not Provided: N/A
  • Teacher Modeling

    will identify the main idea of the first paragraph of “Are You Smarter Than a Fifth Grader?” (provided in Books and Passages), using the strategy of identifying the topic sentence in the paragraph. I will model how to distinguish main details (or the most important details) from secondary details (or details that are less important) in the paragraph. For example, the first and second sentences are secondary details because they are not as important to the main idea of the paragraph, but the third and fourth sentences are main details. They strongly support the main idea of the paragraph.

  • Think Check

    Ask: How did I distinguish main details from secondary details? Students should respond that you used the topic sentence to find the main idea. Then you reread the other sentences and thought about whether they were important to the main idea.

  • Guided Practice

    will work together to determine the main idea of the remaining paragraphs in “Are You Smarter Than a Fifth Grader?” and decide which details are main details and which are secondary details.

  • Independent Practice

    will read “Seven Great Summits,” identify the main idea, and determine which details are main details and which are secondary. (Student Independent Practice is provided below in Teacher and Student Materials.)

Build Student Background Knowledge

Explain to your students that they are going to read a passage about a quiz show. Quiz shows became popular in the U.S. when America was in a technology race with Russia in the 1950s. The nation focused on the best and brightest minds in televised competitions that tested thinking skills and book knowledge. Many early quiz shows were rigged or fixed. When the public found out, the U.S. Congress passed a law outlawing the fixing of quiz shows.

great lesson

Awesome reading passages.

Great ideas for teaching reading.

Thank you for this resource. It allowed me to strengthen their understanding and identification!

Thank you for the reading passage. I am going to accompany it with a graphic organizer to separate the main idea from the secondary details.

Great passages and lesson plans. Thank you!

I love the help. Great lesson plans and easy to follow floor map. Thank You!

This is very helpful information. Thank you

The reading selections will keep students engaged.

great infomation

This is a great skill to teach and review before students are asked to explain their answers in writing (on assessments) and use supporting details.

For Seven Great Summits, I plan to remind my students that a main idea can also be found using a title or subtitle. I will guide them to use the subtitle "A young mountain climber..." as the main idea. Then the main details and secondary details really start to be more clear.
