Summarization Attack!
Reading to Learn Lesson Design
Rationale:
Comprehension is the main goal of reading. We must teach students strategies to
comprehend what they are reading. There are many strategies to make
comprehension easier and summarization is one of the main strategies.
Summarizing is a skill that must be taught to students through teacher modeling.
This lesson will teach students how to summarize an article by learning the
three necessary steps of the summarization process which are deleting
information that is not important or is repeated, highlighting the important and
necessary details by using key words or headings, and finding a topic sentence
that covers the main idea and if there is not a topic sentence make one.

Overhead transparency of National Geographic Article: “Hammerhead Sharks”
Hammerhead Sharks:
This shark's unusual name comes from the unusual shape of its head, an amazing
piece of anatomy built to maximize the fish's ability to find its favorite meal:
stingrays. A hammerhead shark uses its wide head to trap stingrays by pinning
them to the seafloor. The shark's eye placement, on each end of its very wide
head, allows it to scan more area more quickly than other sharks can.
The hammerhead also has special sensors across its head that helps it scan for
food in the ocean. Living creatures' bodies give off electrical signals, which
are picked up by sensors on the prowling hammerhead. The shark hunts alone, and
can find stingrays that hide under the sand on the seafloor. Hammerheads also
eat bony fishes, crabs, squid, lobsters, and other sea creatures.
There are nine species of hammerhead sharks. The great hammerhead is the
largest, and typically measures about 13 feet (four meters) long and weighs
about 500 pounds (227 kilograms). Great hammerheads live in most warm ocean
waters throughout the world.

unimportant details

___ ___ Captured the main idea of
the text
Procedures:
1.
Say: “As a class, we have been learning strategies and techniques that will help
us as expert readers. Today we are going to learn about a technique called
summarizing. Does anybody know what summarizing is? (Allow students to discuss).
Summarizing is taking out all of the unimportant facts and recording the main
ideas in an article or text. Summarizing is a great way to help us understand
and remember what we read.”
2.
Say: “Now we are going to look at the rules for summarization.” Show the poster
(listed under materials) to the students and read the rules out loud. “We are
going to summarize an article. To summarize, we will cut out the unimportant
information and pick out the main points that readers need to understand the
article. Then, we will write a sentence that covers the main points from the
article.”
3.
Say: Now, let's read the article “Hammerhead Sharks” and I will model for you
how to summarize this article. Before we read the article, we need to talk about
some vocabulary from the article that we many not understand. The word prey is
one that I am not familiar with. Does anybody know what this word might mean?
(Allow students to discuss the vocabulary word and use their prior knowledge to
talk about what this word might mean. Help students construct a definition of
the vocabulary word and write theis definition on the board. Repeat this process
with the words anatomy and stingray). Now that we have identified some new
vocabulary words, we are going to read the article “Hammerhead Sharks”.
Book Talk: Hammerhead sharks are a fierce and aggressive type of shark. They
have a unique shaped head that they use to hunt the sea. Let's read this article
to find out more about hammerhead sharks!
4.
Display the hammerhead shark article on the overhead and pass out a copy of the
article to each student. Say: Let's look at the first paragraph together. Follow
along as I read aloud, “This shark's unusual name comes from the unusual shape
of its head, an amazing piece of anatomy built to maximize the fish's ability to
find its favorite meal: stingrays. A hammerhead shark uses its wide head to trap
stingrays by pinning them to the seafloor. The shark's eye placement, on each
end of its very wide head, allows it to scan more area more quickly than other
sharks can.”
5.
Say: Now let's look at the steps on our summarization poster. First, we need to
get rid of unneeded details. Then, we need to select the most important details
from the text and make a list of these details. As I am reading, I can tell that
this article is about how hammerhead sharks use their unusual heads to hunt.
Therefore, I am going to underline details that support this main idea and cross
out the details that don't really matter. For example, when it is talking about
stingrays, I can delete this fact because I know this article is about
hammerhead sharks. As I go through and underline the important details about
sharks and hunting here are the details that I underline:
a.
Shark's unusual head helps it hunt stingrays
b.
Uses its wide head to trap stingrays on the seafloor
c.
Eyes on sides of head help it scan ocean
Now, I am going to take this information and make a one-sentence summary.
“Hammerhead sharks use their wide heads and unusual eye placement to hunt down
prey, including stingrays.” Do you see how I summarized this paragraph? Does
anybody have any questions? Instead of rewriting the entire paragraph, I wrote
one sentence that told me all of the important details from the paragraph on
hammerhead sharks.
6.
Say: Why don't you all try the next paragraph. Read the paragraph silently to
yourselves. Mark out any information that is not needed and highlight the
important information. Once you have finished, try
to summarize the paragraph into one-sentence. (Give the students time to read
and highlight.)
7.
Ask the students, “what did you highlight as important details? What information
did you choose to cross out? Who has a sentence that they think would summarize
this information?” Give students an opportunity to share their answers. Work
with the students as a class to create a good summary. Write this summary on the
board and talk about why it is a good summary (no trivial information, main idea
captured, condense).
8.
Now, on your own I want you to read the next paragraph (paragraph 3) of our
article and create a one sentence summary using the strategies that we have
talked about. Remember to highlight the important information and cross out the
unimportant parts. Write your summary on a sheet of paper. Turn in your summary
and the highlighted article copy to me when you finish.
Assessment:
I will assess the students summaries using the summary checklist listed above. I
will also assess their comprehension by asking them the following three
comprehension questions.
1.
Where do Hammerhead Sharks get their name from?
2.
How do Hammerhead Sharks use their unique shape to catch their
prey?
4.
Would it be safe for you to get into the
water with a Hammerhead Shark? Why or why not?
