Lesson 7: Prefixes & Suffixes - Building Word Parts

🎯 Learning Objectives

  • Students understand that words have parts (root, prefix, suffix)
  • Students can identify common prefixes (un-, re-, pre-) and their meanings
  • Students can identify common suffixes (-ing, -ed, -er, -est) and their functions
  • Students can build words by adding prefixes and suffixes to root words
  • Students use morphological knowledge to decode unfamiliar words

Success Criteria (ākonga-facing)

  • I can identify the prefix and suffix in a word.
  • I can build new words by adding word parts.
  • I can use word parts to help decode meaning.

Kupu / Vocabulary

  • prefix – word part at the start
  • suffix – word part at the end
  • root word – base word
  • morphology – study of word parts
  • meaning – what a word means
  • decode – work out a word

πŸ“¦ Materials Needed

Teacher Materials:

  • Prefix and suffix cards (un-, re-, pre-, -ing, -ed, -er, -est)
  • Root word cards (play, help, kind, jump)
  • Word building mats
  • Whiteboard and markers
  • Morphology chart poster

Student Materials:

  • Individual prefix/suffix cards
  • Root word cards
  • Word building worksheets
  • Pencils and erasers
  • Small whiteboards and markers

1. Warm-Up: Word Detective (7 mins)

Purpose: Introduce the concept that words can be broken into meaningful parts.

Teacher Script: "Today we're going to be word detectives! We'll discover that many words are like puzzles - they have different pieces that fit together."

Discovery Activity:

Write these words on the board and ask students what they notice:

  • play β†’ playing β†’ played β†’ player
  • help β†’ helping β†’ helped β†’ helper
  • kind β†’ unkind β†’ kinder β†’ kindest
Key Discovery: "The root word stays the same, but we can add parts to the beginning (prefixes) or end (suffixes) to change the meaning!"

2. Teaching Common Prefixes (12 mins)

Systematic Introduction: Introduce prefixes one at a time with clear meaning and examples.

un- prefix:
  • Meaning: "not" or "opposite"
  • Examples: unhappy, unkind, unlock
  • Memory: "Un- means NOT!"
re- prefix:
  • Meaning: "again" or "back"
  • Examples: replay, reread, return
  • Memory: "Re- means AGAIN!"
pre- prefix:
  • Meaning: "before"
  • Examples: preview, preheat, preschool
  • Memory: "Pre- means BEFORE!"

Teaching Process for Each Prefix:

  1. Show the prefix card and teach the meaning
  2. Demonstrate with a familiar root word
  3. Have students suggest other words with this prefix
  4. Practice identifying the prefix in different words
  5. Connect meaning to understanding the whole word

3. Teaching Common Suffixes (12 mins)

Systematic Introduction: Introduce suffixes and their functions in changing word meaning or form.

-ing suffix:
  • Function: Shows action happening now
  • Examples: running, jumping, reading
  • Memory: "Doing it now!"
-ed suffix:
  • Function: Shows action in the past
  • Examples: jumped, played, helped
  • Memory: "Already done!"
-er suffix:
  • Function: "One who does" or "more"
  • Examples: teacher, player, faster
  • Memory: "Person who does it!"
-est suffix:
  • Function: "Most" (superlative)
  • Examples: fastest, kindest, biggest
  • Memory: "The most!"
Key Teaching Point: Suffixes can change what kind of word it is (verb β†’ noun) or add meaning (fast β†’ faster β†’ fastest).

4. Word Building Practice (10 mins)

Hands-On Activity: Students build words using root words, prefixes, and suffixes.

Word Building Challenges:

Root Words to Use:
  • play, help, kind, fast
  • jump, read, clean, happy
Building Tasks:
  1. Make a word meaning "not happy"
  2. Make a word meaning "one who helps"
  3. Make a word meaning "most fast"
  4. Make a word meaning "read again"
Differentiation: Advanced students can try building longer words with multiple prefixes/suffixes (e.g., unhelpful, replaying).

5. Independent Practice & Exit Ticket (4 mins)

Exit Ticket Task

"Break these words into parts and write what each part means: unhappy, playing, teacher"

Success Criteria:

  • Emerging: Identifies some prefixes and suffixes correctly
  • Developing: Correctly identifies most parts and explains some meanings
  • Secure: Accurately identifies all parts and explains their meanings clearly
Celebration: "You're becoming word builders! Tomorrow we'll practice using these skills to read and spell more complex words."

πŸ“Š Assessment & Differentiation

Formative Assessment:

  • Observe prefix and suffix identification
  • Check understanding of morpheme meanings
  • Monitor word building accuracy
  • Assess application to new words

Support Strategies:

  • Struggling: Focus on one prefix/suffix at a time, use visual aids
  • Confident: Introduce more complex affixes (dis-, -ful, -ness)
  • ELL Support: Connect to word parts in home language
Next Lesson Preview: We'll practice applying morphology skills to longer, more complex words and improve our spelling strategies.
