Expository Idea Map• Expository idea maps are a series of rectangle arranged to illustrate the structure of the text and the relationship between ideas.
• Student see different pattern in each expository text.

Based on the organizational pattern present in expository test.• Description• Sequence• Cause-effect• Problem-Solution• Compare-Contrast

Expository Idea Map for DescriptionDescription Minerals
Over 2000 different kinds, and all share five characteristics.
Formed in nature , not a lab, and come from the earths crust.
inorganic; not made of living thing or produced by living things.
are solids
definite chemical composition ; always contain same elements in same proportion
has particular crystalline structure; atoms from geometric ; shape or crystal.

Expository Idea for SequenceSequence
Glacial erosion
Glacier moves, melted water seeps into rock, cracks and freezes
Ice wedging causes rock to break apart
Rock part stick to glacier and move with it
Rock parts act like sandpaper and scrapes bedrock and soil
Erosion causes many land forms

Expository Idea Map for Problem Solution
Problem: In early 1800s, Americans in Texas had no loyalty
to Mexico
Mexico owned Texas
Mexico gave land to Americans to develop land and control Indian
control
Mexico insisted Americans worship as Catholics; most were protestants
Mexico banned slavery; most Americans were slave owners
Mexico sent army to enforce law
Solution: They won independence from
Mexico
Stephen Austin and Sam Houston
were leaders
Declared indepence in 1836
and set up Republic of Texas
200 Texans defended the Alamo; were
defeated after 12 days
"Remember the Alamo" became
rallying cry
Defeated Santa Ana at battle of
San Jacinto

Expository Idea Map for Compare-Contrast
Compare-Contrast:Cenozoic Era
66 million years ago
Called age of mammals
Mammal evolved into plant and animal eaters
Ancestor of all modern mammals evolved
Land was shaped by glaciers
Cool dry climate with ice age at end
First humans evolved
Compare-Contrast: Mesozoic Era
250 million years ago
Called age of dinosaurs
First mammals evolved
Birds and flowering plants evolved
Single land mass broke and shaped in to continents
Major changes in environment and
climate
Similar

• Cause and effect are for older students since expository text with this kind of pattern is very confusing.
• Expository structures are more complex; concept dense and the writer expect readers to identify what structure it is.
![Page 9: Expository Idea Map](https://reader034.fdocuments.in/reader034/viewer/2022042515/5537c9594a79596f718b45c5/html5/thumbnails/9.jpg)
• Using the appropriate idea map depends upon the level of the student and the materials you are using. • Younger reader and low level text-
description can use description ,sequence and compare and contrast.• Older reader struggling with middle
school and high school materials can use problem-solution and cause and effect.

• The number of rectangles and arrows depend on the complexity of the text and important ideas, student should have the freedom to add and delete.• Use maps for retelling and summarizing guides.• use idea maps for pre-writing expository text.

Retelling and Note-taking
• This is equated with note taking.•When we retell, we include important elements of the text. An effective note-taker is the same, jotting down important key terms she or he wants to remember.

Main Idea Map
• Struggling reader have difficulties in finding the main idea.• Main ideas are not always explicitly
laid in the text. Some authors expect the readers to generate one.• Students are used to the belief that
main ideas are found in the first paragraph. But this is not true all the time.
![Page 13: Expository Idea Map](https://reader034.fdocuments.in/reader034/viewer/2022042515/5537c9594a79596f718b45c5/html5/thumbnails/13.jpg)
• true all the time.• Struggling reader must be aware that focusing on the topic can aid in finding the main idea• Graphic organizer which help reader locate the main idea.• Provide vehicle for understanding and discussing expository content,.
![Page 14: Expository Idea Map](https://reader034.fdocuments.in/reader034/viewer/2022042515/5537c9594a79596f718b45c5/html5/thumbnails/14.jpg)
• Student will construct a main idea map differently from other students, which is troublesome since most reader think that there is only one main idea. But locating the main idea is not really important. What is important is the student learns to highlight important details and key ideas that explains them.

• For lower levels-use single paragraph
• For higher level- few paragraphs.

Application to English Language Learners
![Page 18: Expository Idea Map](https://reader034.fdocuments.in/reader034/viewer/2022042515/5537c9594a79596f718b45c5/html5/thumbnails/18.jpg)
• Expository text represents a challenge for all students.• Expository is more difficult than narrative
and it is much less frequent in elementary schools.• Moss (2006) recommends teaching
expository text structure because it helps them to ‘predict and confirm meaning in a passage.
![Page 19: Expository Idea Map](https://reader034.fdocuments.in/reader034/viewer/2022042515/5537c9594a79596f718b45c5/html5/thumbnails/19.jpg)
• Lessons using such non-linguistic representation are especially appropriate for students who have difficulty demonstrating their understanding through writing or traditional test-taking formats (Hill and Fynn, 2006; Hedrick, Harmon and Wood , 2003)
• Use of graphic organizer can make expository content more accessible “because the process in preparing arrays of symbolic information helps them build a framework for learning key ideas and vocabulary” (Hernandez 2003)
• Cappelini (2005) comments that learners lose track of big information in their efforts on absorbing the information from the text.
