What text structure or pattern of organization where the similarities and differences of two or more people places things or ideas is explored?

Example 1: In my neighborhood, there is a house everyone thinks is haunted. Dark overgrown bushes surround the yard. The porch creaks whenever you step on it. At night, only a few lights shine. Sometimes, they seem to flicker on and off mysteriously. Imagine a place where it rains every day. Tall trees loom above you. Branches form a green ceiling high in the sky. Plants, vines, and brightly-colored flowers fill every inch of space.
EXAMPLE 2: A book may tell all about whales or describe what the geography is  like in a particular region.

Example 1:
It rained for the first few days of the camping trip. As a result, most of the campers were restless and wanted to go home.

EXAMPLE 2: Weather patterns could be described that explain why a big snowstorm occurred.

Comparison/Contrast:
This type of text examines the similarities and differences between two or more people, events, concepts, ideas, etc.
The text shows how ideas or things are alike or different. Look for words like "best," "more," "better," "less," "worse," "easier," "than."

Example 1: The best time to visit the Rocky Mountains is early fall. The weather is cooler in the fall than in the summer. You will see fewer people and more animals, in the summer it gets very crowded and there are fewer animals to be seen. The fall colors are more beautiful then the usual greenery of summer.
EXAMPLE 2: A book about ancient Greece may explain how the Spartan women were different from the Athenian women.
Comparison/Contrast

Chronological Order/Sequence: This text structure gives readers a chronological of events or a list of steps in a procedure. The writer places events in the order in which they happen.  Look for signal words like "first," "then," "finally," " a few minutes later," "next," "after lunch," "last year."https://www.youtube.com/watch?v=FC5EkKoEu24
Example 1: First, Rhett was late getting to school. Then, he lost his homework. A few minutes later, the teacher asked him to clean out his desk. Now Rhett thinks it will be a bad day.
EXAMPLE 2: A book about the American revolution might list the events leading to the war. In another book, steps involved in harvesting blue crabs might be told

Problem-Solution:
This type of structure sets up a problem or problems, explains the solution, and then discusses the effects of the solution.

Example 1: The city of Taylor has fifteen public swimming pools. In the past, plenty of lifeguards have been available for staffing the pools throughout the summer. Most of the lifeguards were teenagers out of school for the summer. This year, however, not enough lifeguards have signed up to work. The city has started asking healthy retired people to be lifeguards. They will be trained by the city for free if they will agree to work 10 hours per week at a city pool. They will be paid $8 an hour for their work.

The problem: Taylor doesn't have enough lifeguards to staff its city swimming pools.

The solution: Encourage retired people to become certified lifeguards and work at the pools.

Question and Answer:
NOTE: This text structure, although used in test questions and in science and social studies texts is not one featured in out standards. However, I want the students to understand this is also an organizational structure that an author uses to organize his/her writing.
The writer presents a question and then tries to answer it.


Example: Many schools are thinking about this question: Should students be made to wear uniforms? I believe they should not. First, clothing is a very important way that kids express themselves. . .

When we read a nonfiction piece of writing to learn about the world around us, sometimes it is framed in a compare and contrast text structure.

When we read a nonfiction piece of writing to learn about the world around us, sometimes it is framed in a compare and contrast text structure. 

Whether the topic is ancient civilizations or future scientific breakthroughs, we are able to make meaning when we recognize that the text structure presents a compare and contrast relationship. When we, as readers, are guided and coached to readily identify a compare and contrast text structure, we are able to effectively read with purpose and comprehend. Likewise, when we write a nonfiction piece and effectively use a compare and contrast text structure to convey meaning we are able to achieve our purpose.

Compare and Contrast is a text structure or pattern of organization where the similarities and differences of two or more things are explored. It is important to remember that with the compare and contrast text structure the text should be discussing similarities and differences. If the text only discusses similarities, it is only comparing. Likewise, if it only discusses ways that the things are different, it is only contrasting. The text must do both to be considered compare and contrast.

Example: Apples and oranges are both fruits, which means that they have seeds inside of them. Each has a skin, but orange skins are thick and easy to peel. Apple skins are thinner and do not peel easily. Oranges also contain more acid than apples, but both fruits are delicious.

Identifying when the writer is comparing and contrasting is usually not difficult because the speaker will bounce back and forth between two subjects and this pattern is generally pretty easy to recognize.  However, here are some signal words that may indicate that the text is written using the compare and contrast organizational pattern: like, unlike, both, neither, similar, and different.
