									                         Title of Intervention: Main Idea Map

Purpose: The purpose of the main idea map is to teach students to use a graphic
organizer containing the main ideas of an expository passage in order to increase free
recall of the passages and to increase passage comprehension.

Age/Grade Level: This intervention has support for middle grades, 6-8.

Format: Check all that apply
   Individual                                      Small Group
   Dyads                                           Whole Class

Materials Needed:
                      1. Overhead transparencies of practice passages
                  2. Transparencey markers
                  3. Student copies of practice text
                  4. Main idea graphic organizer or blank sheet of paper

Frequency / Duration: One to three full instructional sessions for introducing and
practicing the concept during the first week and then use 2-3 times a week for a
specified amount of time.

Intervention Script:
    1. Introduce the strategy by telling students you can draw pictures or main idea
       maps that help us understand how the ideas of a passage fit together. Present
       the following steps.
           a. Locating the main ideas of paragraphs. Read through a short practice
               paragraph with the class.
           b. On a blank overhead begin building a graphic organizer by writing the
               title of the passage in the center.
           c. Draw a box aound the title.
           d. Tell the students some paragraphs have summary sentences that state
               the main idea of the paragraph and others have implied main ideas,
               which the reader must figure out, based on the key facts or ideas they
               contain.
           e. Go through each paragraph in the practice passage and identify the
               paragraph's main idea. Demonstrate how to summarize the main idea in
               a single, succinct phrase.
    2. Build the main idea graphic organizer. As you summarize each paragraph's main
       idea, write the number of the paragraph and the main idea summary phrase on
       the graphic organizer.
    3. Add key facts.
           a. When you have written the main idea for all the paragraphs onto the
               graphic organizer, return to the passage.
          b. For each paragraph, pull out 2-3 important facts, ideas, or supporting
             details. On the graphic organizer, write these key pieces of additional
             information under the main ideas phrase for each paragraph.
          c. Then draw a box around the main idea and supporting details and move
             on to the next paragraph.
   4. Practice using the graphic organizer as a sudy tool. Demonstrate how the
      completed graphic organizer can be a useful method to summarize and review
      the content of expository passages. Give the students new practice passages and
      have them create their own graphic organizers. Provide feedback and
      encouragement as necessary.


Data Collection: Reading comprehension can be measured through informal reading
inventories, CBM probes, or standardized diagnostic reading achievement tests.
