Review of Lesson 26: Silent Letters

Look at these words and listen to me read them out loud:

debtor 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.

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?

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 destructTurn 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:

newspaperTurn 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 elsewhere peppermint bandwagon counterbalance downcast

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.
