Day One
Supporting ELs
The lesson introduces the example
words using concrete objects and
demonstrations. Continue to support ELs
by providing concrete examples whenever
possible to help explain word meanings.
Review Prefix Assimilation adFocus Words: advertise, appreciate, assessment, attribute, accommodate
Write the focus words on the chalkboard. Ask students what these words have in
common. (The prefix ad- or one of its spelling variations.)
Ask a volunteer to explain in his or her own words why the prefix changes spelling.
All the initial example words have Spanish
(The /d/ sound is absorbed into the sound at the beginning of some words.)
cognates, although the spelling of the
quar- prefix is slightly different. Use these
to help Spanish speakers understand the
meanings of the prefixes: el cuarteto/
quartet; el quinteto/quintet; el octeto/
octet; el decimal/decimal; el centímetro/
centimeter.
Introduce Greek and Latin Prefixes for
Numbers quadr-/quar-, quint-/pent-, oct-,
dec-, cent-
The Greek and Latin number prefixes
occur in many different languages. The
prefixes are visible in the Spanish cognates, Model
including: el cuadrángulo/quadrangle;
Explain that in this lesson, students will learn some Greek and Latin number prefixes.
la quintaesencia/quintessence; el
pentágono/pentagon; el centenario/
Hold up four of the same type of object, such as books. Say: I have a quartet of
centennial.
books. Quartet is another way of saying “a group of four.”
Next, hold up five of the same type of object, such as pencils. Say: I have a quintet of
pencils. Quintet means “a group of five.”
Blending Practice
If some students have difficulty reading the
words, help them read the words syllable
by syllable. For example, point to the word
quartet on the chalkboard. Show how you
divide the word into two syllables between
the two consonants, r and t. Explain that
you now have two closed syllables, one
with an r-controlled vowel sound and
one with a short vowel sound. Read each
syllable and then blend the syllables
together: quar/tet: quartet. Continue
to support students who need help with
blending throughout the week, using the
example words used in the lesson.
Write the words quartet and quintet on the chalkboard and circle the prefixes quarand quint-. Say: The prefixes quar- and quint- are number prefixes that mean
“four” and “five.” Other number prefixes include oct-, which means “eight,” dec-,
which means “ten,” and cent-, which means “one hundred.”
Write the words octet, decimal, and centimeter on the chalkboard. Circle the prefix in
each. Say: The prefix oct- means “a group of eight.” I recognize the words decimal
and centimeter. A decimal is “a number expressed in base ten.” A centimeter is
“one hundredth of a meter.”
Guide
Show students the anchor poster and tell them to use it as a reference as they work
with the number prefixes.
Write the words quarter, quintuplets, octagon, decathlon, and century on the
chalkboard. For each word, ask a volunteer to identify the prefix and its meaning,
and to give the meaning of the word.
©2010 Benchmark Education Company, LLC. All rights reserved.
Ask the rest of the class if they agree with the volunteer’s definition. Guide students
to the correct meaning of each word.
Teachers may photocopy the reproducible pages for classroom use.
No other part of the guide may be reproduced or transmitted in whole or
in part in any form or by any means, electronic or mechanical, including

Assessment Tip
Ask students to work with a partner to create sentences in their word study
notebooks using five of the words on the chalkboard, one with each of the prefixes
quar-, quint-, oct-, dec-, and cent-.
Note which students do not volunteer
during the discussion of word meanings,
or who seem to lack understanding of the
meanings of the prefixes. You may want
to review Greek and Latin roots with these
students, or have them create a reminder
chart like the one shown here of the
meanings of the prefixes.
Spelling Greek and Latin Number Prefixes
Unit Spelling Words: quartile, quadrangle, quintuplets, pentagon, octave,
decimal, centennial, centipede
Write the prefixes quadr-/quar-, quint-/pent-, oct-, dec-, and cent- in a row on the
chalkboard. Write the words quartile, quadrangle, quintessence, and pentagon on
the chalkboard under the appropriate headings.
Explain that Greek and Latin had different words signifying “four” and “five,”
so there are two different spellings of these two prefixes. Say: Both quar- and
quadr- mean “four.” And quint- and pent- mean “five.” Write 4 and 5 above the
appropriate columns on the chalkboard.
Write the remaining spelling words on the chalkboard in the appropriate
categories. Write 8, 10, and 100 above the corresponding columns.
Have students discuss and speculate about the meanings of the spelling words and
how the prefixes influence those meanings. Have students write the spelling words
in their word study notebooks and circle the words they are least familiar with. Tell
them to work with a partner to create sentences for these words.

quadr-/quar-, quint-/pent-, oct-, dec-, centSay the following sentence: That quartet is the quintessence of musical talent.
Ask students what they remember about words such as quartet and quintessence.
After students have explained the meanings of quar- and quint-, ask them for the
other prefixes with the same meanings. (quadr- and pent-) Then ask them for the
prefixes meaning “eight,” “ten,” and “one hundred.” (oct-, dec-, and cent-) Ask
volunteers to think of words with these prefixes and write them on the chalkboard.

Providing Support
Students may find it difficult to define
quintessence. Explain that in ancient times
there were four essences: air, earth, fire,
and water. The fifth essence came after
these and was the highest essence. So
quintessence means “for the highest or
purest expression of something” or “the
best example of.”
Home/School Connection
Have students take home BLM 6 to
complete with a family member. Students
can also take home the word cards and
share their sorts with a family member.
Teacher Word Cards: same as BLM 3
Teacher Category Cards: quadr-/quar-, quint-/pent-, oct-, dec-, centPlace the category cards in a row in a pocket chart so that students can see them.
Hold up the word card quarter.
Think aloud: The word quarter starts with the prefix quar-, which means “four.”
Quarter belongs in the chart under quadr-/quar-.
Have students help you sort the remaining cards. In addition to telling you which
category to place the word in, ask students to state the meaning of the word’s prefix.
The word percentage is an oddball in that the prefix per- has been added to the
prefix cent-, so you may need to clarify this word’s relationship to the category.
Buddy Sort
Give pairs of students the category cards and the word cards from BLM 4 and have
them sort the words by prefix spelling. Ask students to explain how the prefix is
reflected in the word’s meaning as they sort each word.
Spelling. Ask students to re-create the pattern sort in their word study notebooks
with the spelling words.
Supporting ELs
Because some ELs may not have someone
at home who speaks English well enough
to work with them on BLM 6, make
sure that they understand what they are
supposed to do on the BLM.

Day Three
Buddy Meaning Sort
Give pairs of students the category cards four, five, eight, ten, and one hundred
and the word cards from BLM 5.
Explain that in this sort they will categorize words by the meaning of their prefix.
Say: Your partner will read you a word. Listen for the prefix and determine
its meaning. Tell your partner in which category the word belongs. Take turns
reading and sorting and continue until you have sorted all the words.
When pairs have finished, ask them to double-check their work and make sure
they sorted all the words correctly.
Applying Meaning. Give students BLM 7 and have them choose the correct words
to complete each sentence. Remind students to check their spelling.
Oddballs
Students may wonder about the derivation of the words October and December.
Based on the meanings of the prefixes, it would be logical for October to be the
eighth month and December to be the tenth month of the year, instead of the
tenth and twelfth months.
Explain that the first Roman calendar had ten months in total. A month lasted from
one full moon to the next, and the calendar didn’t begin until the spring equinox
in March. The calendar left out two full months of winter. So, by that calendar,
October was the eighth month and December was the tenth, and last, month.
During the reign of Julius Caesar, the calendar was changed to the one we use
today.

their meanings.
Providing Support
ELs and struggling readers may have
difficulty completing BLM 7 on their own.
Have them work with a partner to read
and complete it.
Home/School Connection
Give students BLM 8 to complete with a
family member. Explain that they are to do
the same thing they did on BLM 7 in class.
Supporting ELs
Make sure that ELs understand what to do
on BLM 8 since there may not be anyone
at home who speaks English well enough
to help them complete it.

more about, such as a field or forest. Remember to get permission to take
inventory in the area you’ve chosen, if necessary.
To set up your nature inventory, simply use a long piece of rope and
wooden stakes to mark off a plot of land that is about twenty square feet.
As another option, you might wish to rope off a larger area and divide
it into quadrants; that way, you and three friends can each do your own

Give students a copy of the passage on BLM 9. Tell them that they will read the
passage and underline the words with the Greek and Latin number prefixes they
have learned.

consider including different features in each quadrant, such as a grassy field
in one quadrant and a bubbling stream in another quadrant.
To take your nature inventory, examine every last centimeter of your
square. Record all of the flora and fauna you find, from flowers and trees to
tadpoles and centipedes. If possible, complete a nature inventory for this
plot of land at least once during each quarter of the year. An inventory taken
in December will be very different from one taken in May or in October, and
you might learn some surprising things!

Home/School Connection
Have students take the reading passage on
BLM 9 home to read to a family member
and point out the words with Greek and
Latin number prefixes.
Have students ask older family members
if they have ever celebrated a centennial
or known an octogenarian. Students can
collect oral histories about these topics.
Supporting ELs
Make sure ELs know the meanings of the
spelling words. Before student pairs use
BLM 11, have the partners tell each other
oral sentences using the spelling words.
Dictate the following sentence and have students write it on their papers:
The scientist measured the large centipede and found that it was in the fourth
quartile for length.
Write the words and sentence on the chalkboard and have students self-correct their
papers.
Spelling Practice
Give pairs of students Spelling Peer Check (BLM 11). While one student reads the
spelling words from his or her word study notebook, the other student writes the
words in the First Try column. After the second student has spelled the words,
the first student places a check mark next to words spelled correctly.
For the second try, the first student may prompt the second student by sounding out
the words that were spelled incorrectly the first time. If the second spelling attempt is
correct, the first student places a check mark in the Second Try column.
Then students switch roles.

Suggestions for Independent Practice
Go Fish. Give pairs of students a set of word cards that has been selected so
that there are three words with each prefix, quadr-, quar-, quint-, pent-, oct-,
dec-, and cent-. Each student draws six word cards; the rest of the cards remain
facedown in a pile. The first student asks if the other student has any words with a
certain prefix. The other student hands over a word with the prefix, if he or she has
one, or says “Go fish,” in which case the student draws a card from the pile. When
students have three of a kind, they lay the cards on the table. The object is to get
rid of all one’s cards.
Scrambled Words. Have students scramble ten words from the word cards and
write them on a sheet of paper. Students exchange papers with another student
and try to unscramble the words. Students can time themselves with a stopwatch
and see who can unscramble the words the fastest.
Matching Definitions. Students select eight to ten word cards and write
definitions in their own words. Students may consult a dictionary as they write
their definitions. After exchanging definitions and word cards with a partner, the
student matches each word with its definition.
Blind Writing Sort. To practice their spelling, give pairs of students one set of
category cards and one set of word cards. Have them write the categories in a row
in their word study notebooks. The first reader chooses a card and pronounces
the word without showing the card, and his or her partner writes the word in the
correct category. Remind students to switch roles.
