Review of Lesson 26: Silent Letters
Look at these words and listen to me read
them out loud:
debtor
knack
Remember that some letters are silent. Did
you hear a /b/ sound in the word debtor? Did
you hear a /k/ sound in the word knack?
I will show you some more words. When these words
appear, read them to yourself. When I point say them
out loud. Identify the silent letter in each one.
know
thumb
science
doubt
Some longer words are made up of a root or root
words plus a prefix and suffix. Turn to your partner
and see how many prefixes and suffixes you can
remember in 45 seconds.
How many of these did you remember?
un-, dis-, re-, -able, -ly, -ful, -tion
Look at the words below, then decide which letters are silent and
which column they should be sorted into in the chart below. Be
sure you can read each of the words to your partner.

Review of Lesson 27: Greek and Latin
Word Parts
Look at these words and listen to me read them out
loud:
construct
destruct
Turn and tell your partner what these two words have
in common.
Give a thumbs up if you said that they both share the
word part struct. Remember that struct is a Latin word
part meaning “to build”. When you come to a longer
word, looking for familiar Greek and Latin word parts can
help you determine its meaning.
Copy the chart below and write each word under the correct
word part. Be sure you can read each word aloud.

Review of Lesson 28: Compounds
Remember that compounds are words made up of
two words put together. Look at this word:
newspaper
Turn and tell your partner what two words form
newspaper.
News and paper are the two words that form newspaper. A
newspaper is paper that has the news on it.
When you encounter a compound word, use your
knowledge of the pronunciation of the shorter words to read
the longer word.
Look at the following compound words. On a piece of
paper divide each compound word into two shorter
words. Read the words to a partner.
superstructure

bandwagon counterbalance downcast
super/structure
else/where pepper/mint
band/wagon counter/balance down/cast
Review of Lesson 29: Prefix +Root Word + Suffix
Look at this word and listen to me read it out loud:
unkindly
Turn and tell your partner the prefix, suffix, and root
word in this word.
Give a thumbs up if you said that the prefix is un-, the
suffix is-ly, and the root word is kind.
Remember that many longer words are made up of a
root or root word plus a prefix and suffix. It is sometimes
helpful to break a longer word into smaller parts to
determine its pronunciation.
Look at this chart. Identify the prefix, suffix, and root or
root word in each longer word. Decode each word part
and then read the longer word.
