Sub-topic: Using Prefixes and Suffixes to Enhance Vocabulary

 

Learning Objectives

By the end of the lesson, students should be able to:

1. Define prefixes and suffixes.
2. Identify common prefixes (un-, dis-, re-, pre-, mis-) and their meanings.
3. Identify common suffixes (-ful, -less, -ness, -ment, -tion, -er) and their functions.
4. Explain how prefixes and suffixes change word meanings and grammatical functions.
5. Use newly formed words to improve vocabulary in paragraph writing.

 

Previous Knowledge

Students already know:

• How to construct sentences and paragraphs.
• Basic sentence types and paragraph structures (Weeks 1–8).

 

Instructional Materials

• Textbook: English Language textbooks for Grade 7
• Teaching aids: Word cards with prefixes/suffixes, sample paragraphs, chalkboard/marker board
• Students’ notebooks and writing materials

 

Lesson Development – ABC Model

A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes

• Teacher writes the words: happy, kind, read on the board.
• Ask students: “Can we change these words to mean the opposite, or make them into nouns/adjectives?”
• Students share suggestions (e.g., unhappy, kindness, reader).
  Teacher’s Role: Lead discussion and introduce the concept of prefixes and suffixes.
  Learners’ Role: Suggest word changes, observe, and participate actively.

 

B – Building Knowledge (Main Lesson Body)

Time: 25–30 minutes

Teacher’s Role (Expanded):

1. Define and Differentiate Prefixes & Suffixes

• Prefix → Letters added before a root word to change its meaning.
• Example: do → undo (opposite), write → rewrite (again).
• Suffix → Letters added after a root word to change its form, meaning, or part of speech.
• Example: happy → happiness (adjective → noun), care → careless (removes quality).

2. Introduce Common Prefixes with Multiple Examples

• un- (not, opposite): unhappy, unfair, unclear.
• dis- (not, opposite): dislike, disconnect, dishonest.
• re- (again): rewrite, rebuild, reread.
• pre- (before): preview, preheat, preschool.
• mis- (wrongly, badly): misbehave, misunderstand, misspell.

👉 Sentence Examples:

• The boy was unhappy because he lost his toy.
• I had to rewrite my notes neatly.
• We watched the movie trailer to preview it.
• He often misunderstands the teacher’s instructions.

3. Introduce Common Suffixes with Multiple Examples

• -ful (full of): joyful, helpful, beautiful.
• -less (without): careless, hopeless, tireless.
• -ness (state, quality): kindness, darkness, happiness.
• -ment (process/result): enjoyment, development, agreement.
• -tion (action/result): completion, celebration, invention.
• -er / -or (person/thing that does): teacher, singer, actor, driver.

👉 Sentence Examples:

• The children were joyful during the celebration.
• It is dangerous to be careless when crossing the road.
• We felt great happiness when our team won.
• The project is near completion.
• The teacher explained the lesson clearly.

4. Show How Words Change Meaning and Function

• Happy (adjective) → Happiness (noun).
• Teach (verb) → Teacher (noun).
• Care (verb/noun) → Careless (adjective).
• Agree (verb) → Agreement (noun).

5. Demonstrate Using Prefixes and Suffixes in a Paragraph
   “Our teacher asked us to rewrite our essays neatly. Some students were careless, but others showed great kindness by helping their friends. We all felt joyful when the task reached completion.”

 

Learners’ Activities (Expanded):

• Listen carefully and copy examples.
• Identify prefixes/suffixes from a word list (e.g., happiness, preview, dishonest).
• Form new words by adding given prefixes and suffixes to base words (e.g., play → replay / playful; dark → darkness / darken).
• Write short sentences using their newly formed words.
• In pairs, write a short paragraph using at least two prefixes and two suffixes.

 

Assessment Checks (Expanded):

• Oral Questions:
• “What does the prefix re- mean?” (Again)
• “Give me one word with the suffix -ful.” (Joyful, helpful, etc.)
• “What is the difference between a prefix and a suffix?”
• Quick Drill: Teacher gives root words → Students add prefix/suffix.
• Base word like → dislike, likely, likeness.
• Base word care → careless, careful, caring.
• Base word play → replay, playful, player.

 

Notes (Expanded & Detailed):

• Prefix = letters at the start (changes meaning).
• Suffix = letters at the end (changes form/part of speech).
• Adding prefixes/suffixes enriches vocabulary and helps in writing variety.

Examples of Changes in Part of Speech:

• Dark (adjective) → Darkness (noun).
• Act (verb) → Action (noun) → Actor (noun, person).
• Use (verb) → Useful (adjective) → Useless (adjective).

 

C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes

Summary:

• Teacher reviews meaning and use of prefixes and suffixes.
• Highlight the importance of using them in writing to enhance expression and clarity.

Evaluation Method:

• Exit slip/quiz:

1. Define a prefix and a suffix.
2. Give one example of a word with the prefix re- and explain its meaning.
3. Write a short paragraph (3–5 sentences) using at least three words formed with prefixes or suffixes.

• Teacher reviews responses and provides oral feedback.

Assignment:

• List 10 base words and create new words using prefixes or suffixes. Write one paragraph using at least five of these newly formed words.

 

Differentiation / Inclusive Strategies

• Struggling Learners: Provide a list of base words with suggested prefixes/suffixes.
• Advanced Learners: Challenge them to use less common prefixes/suffixes (e.g., anti-, co-, -ology).
• Students with Disabilities: Use visual aids, word cards, and oral exercises for reinforcement.
