Vocabulary Strategy

Use word structure to determine word meaning.

INTRODUCE

Remind students of strategies they can use when they encounter unknown words.

Look for word parts, such as Greek or Latin roots.
Think about the meaning of the root and what it tells you about the word's meaning.
Try the meaning in the sentence to see if it makes sense.

TEACH

Discuss the steps on p. 540 for using word structure.
Have students read "Looking for the Past," paying attention to how vocabulary is used.
Model using a Latin root to determine the meaning of ventured.

MODEL I know that the Latin
root ven- means "to come."
The rest of the sentence shows me ventured is something scientists did in places few others would go. So I think ventured means "dared to come or go." That meaning makes sense; "These scientists dared to go into places few others would go."

then… use Tested Vocabulary Cards.

If… students need more practice with the lesson vocabulary,

Word Structure

PRACTICE AND ASSESS

Have students determine the meanings of the remaining words and explain the strategy they used.
Point out that in some words with Greek or Latin roots, a few letters may differ from the original word. For example, the Latin root for torrent comes from torrens. Some dictionaries include Greek and Latin roots or they can be found online by searching for Greek and Latin roots.
If you used a question-and-answer activity (p. 540b) to introduce vocabulary words, revisit these questions after students read "Looking for the Past" and give students an opportunity to revise their answers. Then challenge them to come up with their own vocabulary questions for classmates to answer.
Have students complete Practice Book p. 215.

WRITE Writing should apply

vocabulary words appropriately to describe features of the chosen illustration.

LOST CITY: The Discovery of Machu Picchu

As you read “Looking for the Past,” look for
words with Greek or Latin roots to help you
figure out the meanings of the words.

Try the meaning in the sentence. Does it
make sense?

What is the meaning of the Greek or Latin
root? How does it affect the meaning of the
unknown word?

Look at the unknown word. Try to identify a
Greek or Latin root.

Word Structure Many English words have Latin
or Greek roots. For example, the Latin word terra
means “earth, land.” Part of it appears in words
such as terrain (surface of the ground) and
territory (an area of land). The Latin word gloria
means “praise”; part of it appears in words such
as glorify, meaning “to praise.” You may be able
to use Latin and Greek roots to help you figure
out the meaning of an unknown word.

that fall in a raging torrent.
They have found ruins of places people built long ago.
These may look like rocks to
us, but they are glorious to
these scientists. Imagine the
little team of scientists as they discover terraced fields on the
side of a mountain. These
show that people long ago
were clever farmers. Think of
the scientists as they look at
beautiful temples made of
granite or marble. These show
that people long ago had beliefs. Watch as the scientists carefully
          uncover clay pots and                carvings. These show
                   that people long
                      ago were artistic
                       and loved beauty.

Some scientists study the
past. They look at objects and
buildings from past civilizations.
They have curiosity about people
who lived long ago. How did they
live? What did they eat? What
did they do every day? Did they
read and write? Thanks to these
scientists, we have learned a
great deal about long-ago people.
These scientists have
ventured into places that few
others would go. They have cut
their way through jungles with
thickets full of dangerous animals.
They have climbed steep
mountains and slipped
on rocks. They
have crossed
mountain rivers

	Access Content Use ELL Poster 22 to preteach vocabulary. Choose from the following to meet language proficiency levels. Beginning Help students use word structure to determine meanings of other words from the text, such as curiosity, uncover, and dangerous. Intermediate Have students create a word rating chart prior to reading. Advanced Teach the lesson on pp. 540–541. Have students report on home-language terms for some of the vocabulary words. Resources for home-language words may include parents, bilingual staff members, bilingual dictionaries, or online translation sources. Word Structure Brainstorm words that use terra (earth, land), gloria (praise), and ven (come). Think about meaning to be sure their words are related to the root word.
