1. Base Words Mrs. Marino Houghton Mifflin, Reading, grade 3
Extra Support Handbook
Pages 14-23

2. Warm-Up/Academic Language
Base Words = smaller words
lock (noun/thing or verb/action)
Prefix = beginning attachment
unlock (verb/action)
Suffix = ending attachment
locked (verb/action)
Prefix + base word + suffix = longer word
Unlocked (verb/action)

3. Practice Base word: tie (noun/thing or verb/action)
Prefix: untie (verb/action)
Suffix: tied (verb/action)
Entire Combination: untied (verb/action)

4. More Practice Base Word: plug (noun/thing or verb/action)
Prefix: unplug (verb/action)
Suffix: plugged (notice the “gg”)
(verb/action)
Entire Combination: unplugged

5. Phonic/Decoding Strategies
Syllables: Break words into smaller chunks to decode
un – open – ed = unopened
*un- means “not”:
unpaid = not paid
uneven = not even

6. Examples *Hint: over- = too much -ed = past action
re- = to do again -ing = present action
pre- = to do before -ful -= full of

7. “Use”
Base word: use
Activity: How many words can you make by adding a prefix or suffix to this word?
Try these prefixes and suffixes:
-ed, -ing, -ful, over-, re-
Don’t forget the spelling rule:
If you add a suffix that begins with “e”, drop the extra “e” at the end of the base word.

8. Guided Practice How might each character be feeling?
Support your answer with examples from the dialogue.
How many words can you locate that have a prefix or suffix?
What are the two base words that are used with the prefixes and suffixes?
Write a new sentence using each of the base words.
Share the sentence with your partner.

9. Apply What You Know Read the directions for each section.
Label your answer sheet 1-10.
Neatly print your answers on your answer sheet, next to the correct numbers.
Write the entire word for numbers 7-10.
We will check the answers together.
*If you finish early, turn your paper over and write a new base word and as many variations of the word that you can think of on the paper.*

10. Follow Through Which word is common (base word)? re + play = replay
play + ing = playing

13. Apply Look in the story for more base words contained in larger words.
Write five words on your answer sheet as math equations:
