WHAT IS POWER VOCABULARY?
ower Vocabulary is a systematic and individualized approach to vocabulary development
that enables teachers to assist students to improve their reading comprehension skills.
Power Vocabulary consists of two word groups—specialized and general-usage words.
P
Specialized words label concepts
that support subject matter. These
words are the technical vocabulary
of a content area that is used in a
particular area. In science,
specialized words include
biodiversity and predator. In history,
specialized words include
hieroglyphic and chariot. Specialized
vocabulary also includes words we
use every day that take on
specialized meanings in a particular
content area. For example, the word
bill takes on different meanings
when we talk about money (dollar
bill or electric bill) than when we
talk about government (a bill that
becomes an act or a law).
General-usage words are the words
that have widely acknowledged
meanings and that hold the content
of a passage together. These words
are selected because some readers
may not be familiar with them.
Examples of general-usage words
are morose and diligent.

Words You Know and Words to
Know
◆ Ask students to draw a four-column chart and
label the columns “I don’t Know,” “I’ve seen or
heard but don’t know the meaning.” “I think I
know the meaning,” and “I know the meaning.”
Present each word and its sample sentence to
students. Ask them to write the word in the
column that shows how well they know the
meaning of the word.
Memory Game
◆ Copy the word and definition pages on separate
sheets of paper. Cut out the cards and place them
facedown on a table. Have students play a
memory game by matching words and
definitions. Students should read the words and
definitions aloud each time they have a match to
reinforce the pronunciation and definition.
Challenge: Use correction fluid or tape to cover
the vocabulary words on the definition cards.
Matching
◆ Copy the word and definition pages on separate
sheets of paper and cut out the cards. Paste the
word cards around the edge of tagboard. Ask
students to attach the definitions to their words
using clothespins.
◆ Have students create their own vocabulary cards
for unfamiliar general-usage or content words as
they read KIDS DISCOVER.
S k i m m i n g t h e Te x t
◆ Help students practice skimming text. Read a
sentence or word and the page number in the
magazine where it is located. (The sentences and
page numbers are provided on the definition side
of the cards.) Model how to skim the page for
the word or sentence. Then have students
practice skimming by looking for other words or
sentences.
Challenge: Give students a sentence without the
page number. Encourage them to skim the
magazine for the appropriate topic pages and
then skim for the word.
Dictionary Skills
◆ Practice dictionary skills by asking students to
find the guide words on the page where a Power
Vocabulary word is located in a dictionary. Also
ask students to search for multiple meanings of
words, synonyms, antonyms, and other word
forms or parts of speech for the word.
Jo u r n a l W r i t i n g
◆ After working with the words and definitions,
encourage students to use the words when
writing essays and in their journals.
Dangling Definitions
◆ On sturdy paper, make enlarged copies of the
word and definition cards printed back-to-back
on study paper. Punch a hole in the top center of
each card and attach to the ceiling with string.❖
