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

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 (The base word is the simplest form of the word.)
11
Discussion and Work The teacher is working on the math review.
Read the sentence. Identify the three words with base words. Where is the base word in teacher? teach + -er = teacher certain verbs + -er = noun
12
Practice Turn to “The Lost and Found”, page 20.
Find the word “teacher.” The base word is ________________. Look for the word “entered.” Remember: Look for small words within a bigger word Break the word into “chunks” Ask, “Does this word make sense in the text?”
13
Apply Look in the story for more base words contained in larger words.
Write five words on your answer sheet as math equations: groan + ed = groaned *Discuss your answers with your desk partner. *Write each word in a sentence of your own.
