1. Writing a Summary of
Nonfiction
2. Essential Questions
 What is a summary?
 What makes a good summary?
 How can I write a summary of
nonfiction?
3. What is a summary?
A. A summary is all of the ideas from a
text, written in your own words
B. A summary is your opinions about a
text
C. A summary is a shortened form of a

4. What is a summary?
A. A summary is all of the ideas from a

B. A summary is your opinions about a
text
C. A summary is a shortened form of a
text, with all of the main ideas
D. A summary is a review of a text,
with main ideas and your opinions
5. Why do we write
summaries?
Readers can write a summary of a text to
let someone else know the main ideas
6. Why do we write
summaries?
Summarizing a text helps you to
understand it—as you figure out the
most important ideas, your brain is
engaged in understanding the text
7. Why do we write
summaries?
• Students often write summaries as a
school assignment
• Summaries are also included on tests,
to see how well you understood a text
8. How long should a summary
be?
It depends!
9. How long should a summary
be?
• The length of a
summary depends
on the length of
the original text
• A summary should
always be shorter
than the original
text
10. What makes a good
summary?
Here are four basic rules for writing a
summary of nonfiction:
 Include the important ideas from the text
 Put ideas in your own words
 Leave out little details and repeated
information
 Use the text structure of the text

 Put ideas in your own words
 Leave out little details and repeated

 Use the text structure of the text
12. Include important ideas from the
text
This is easy to say, but sometimes
hard to do! As you read, it’s
important to think about what ideas
are most important to the author
13. Include important ideas from the
text
Many butterflies depend on
certain plants to survive. As
adults, butterflies drink nectar.
But caterpillars eat leaves. Some
caterpillars only eat the leaves of
specific plants. Monarch
caterpillars, for example, eat
only milkweed.
If butterflies cannot find the food source they need for their
eggs, the next generation will not survive. When habitats are
changed, such as when wetlands are drained or forests are
cleared, butterfly populations may drop dramatically.
According to the Xerxes Society, an invertebrate conservation
group, over 50 kinds of U.S. butterflies are at risk.

18. Finding important ideas
• What strategies do you use to find
important ideas in a text?
• Why do you think this is important
for summarizing?
19. What makes a good
summary?
 Include the important ideas from the text
 Put ideas in your own words
 Leave out little details and repeated
information
 Use the text structure of the text
20. Putting ideas in your own words
• Putting ideas in your own words is
also called paraphrasing
• Instead of just copying down the
author’s words, we need to use our
own words
21. Putting ideas in your own words
Can you paraphrase this sentence
from the text?
Many butterflies depend on certain
plants to survive.
22. Putting ideas in your own words
Hint: Try using synonyms for
important words
Many butterflies depend on certain
plants to survive
23. Putting ideas in your own words
Hint: Try changing the order of ideas
Many butterflies depend on certain
plants to survive
24. Putting ideas in your own words
Here’s one way to paraphrase the sentence.
How does it compare to yours?
Butterflies need specific plants to live
Original Text:
Many butterflies depend on certain plants to
25. Paraphrasing
There are some words that you can’t change
when you paraphrase. These key words are
the important words from the passage.
For example, in the
passage that we
read, the words
butterfly and
caterpillar cannot be
replaced
26. What makes a good
summary?
 Include the important ideas from the text
 Put ideas in your own words
 Leave out little details and repeated
information
 Use the text structure of the text
27. Trivial Details
Small details can be called “trivial
details”—they might be interesting,
but are not important to the main
ideas of the passage
We do not need to include these
small details in summaries
28. What small details do you notice?

32. Repeated Ideas
Authors also might repeat ideas. When
the same idea is restated, we only need
to include it once in a summary.
33. What makes a good
summary?
 Include the important ideas from the text
 Put ideas in your own words
 Leave out little details and repeated
information
 Use the text structure of the text
34. Using text structure
The text structure of a text refers to
how the text is organized
 Description
 Cause and Effect
 Chronological Order
 Problem/Solution
 Compare and Contrast
35. Using text structure
When you look at the text structure of a
text, you can find the big ideas and see
how to organize your summary
 Description
 Cause and Effect
 Chronological Order
 Problem/Solution
 Compare and Contrast
