Target Skill Use compare and
contrast.
Target Skill Monitor and fix up to
compare and contrast.
INTRODUCE
Write "Best Friends" on the board.
Tell students to think of the ways in
which they and their best friend are
alike and different. Tell them to write
three to five sentences that compare
and contrast the two of them.
Have students read the information on
p. 380. Explain the following:
  • Recognizing a compare/contrast organization can help us adjust our reading and understand the selection better.
  • Monitoring our understanding
    of a selection and "fixing up"
    what we do not understand
    helps us notice the
    comparisons and contrasts
    an author is making.
Use Skill Transparency 15 to teach
compare and contrast.
TEACH
1 SKILL Use paragraph 1 to model
how to identify when an author
is comparing or contrasting.
Think Aloud MODEL The first word in
the article, although, tells me that the author is going
to write about the differences between two things. If I continue to read, I learn that volcanoes are not all the same.
2 STRATEGY Use paragraphs
2 and 3 to model how to monitor
and fix up in order to understand
the selection better.
Think Aloud MODEL If I'm confused, I
stop and reread or read
more slowly in order to
understand better. For example, why does the author say that what happened next was a surprise? The ground lifted fifteen feet. That would be surprising!
PRACTICE AND ASSESS
SKILL The selection says that
unlike most volcanoes, Paricutín
became a mountain very
quickly. The word yet is a clue
that the author is going to
make a contrast.
STRATEGY Students should slow
their reading or reread the
second paragraph to see
how Paricutín is similar to
other volcanoes.
WRITE Have students complete
steps 1 and 2 of the Write to
Read activity. You might consider
using this as a whole class
activity.

Skill
When you compare and contrast, you
tell how two or more things are alike
and different.
Compare
and Contrast
1
Skill Here is
a detail that tells
one way Paricutín
is different from
most volcanoes.
     Although some volcanoes seem silent, they
may still erupt one day. Others are dead and
will not erupt again. Most volcanoes grow
into mountains over thousands of years. Yet
one, called Paricutín, erupted from flat land
and grew quickly.
Strategy
Active readers check their understanding as
they read. Reading more slowly helps you
notice details, key words, or other clues the
author uses in comparing and contrasting.
Strategy: Monitor and Fix Up
Strategy This might
be confusing. If you
are having trouble
understanding, slow
down. A comparison
between Paricutín
and other volcanoes
is coming up.
2
     One day in 1943, a Mexican farmer noticed
a new crack in his field. Then he felt the earth
shake. What happened next was really a
surprise. The farmer saw the ground lift up
about fifteen feet out of the crack! As in
eruptions of other volcanoes, ash began
pouring out, and the air smelled like rotten eggs.
Write to Read
2.
1.
Use your graphic organizer to
write a paragraph comparing
Paricutín with other volcanoes.
If you missed some details, go
back and read the article
more slowly.
Make a diagram like the one
above. Write “Paricutín” in one
circle and “Other Volcanoes”
in the other. As you read “From
Cornfield to Volcano,” compare
and contrast by writing details
in the diagram.
     Like other volcanoes, Paricutín damaged
farms and towns. Its latest eruption was in
1952, nine years after its first.
     By the next morning, the new volcano had
grown thirty feet. At the end of the week, the
volcano was 450 feet high. In two months,
Paricutín grew 1,000 feet!

Beginning/Intermediate For a Picture It! lesson on compare and contrast,
see the ELL Teaching Guide, pp. 99–100.
Advanced Before students read "From Cornfield to Volcano," have them
share what they know about volcanoes.
Target Skill Compare and Contrast Revisit the Venn diagram to illustrate the skill. Instead of best friends, ask students to compare and contrast an airplane and a car. Label the left circle "Airplane" and the right circle "Car." Elicit details and facts about both types of transportations, and fill in the Venn diagram. When you have three to five details about each type, discuss how planes and cars are alike and different. Then compose several sentences with students that compare and contrast planes and cars.
