Session Duration 

 90 Minutes

Introduction Activity (20 minutes):

Concept Building 

Objective:

To introduce the meaning and function of prefixes.

Steps:

Begin with a question: “What does unhappy mean? Can you find the smaller word inside it?”

Use the whiteboard to break down words:

  • un + happy = unhappy

  • re + play = replay

  • dis + like = dislike

Highlight how the meaning changes when a prefix is added.

Ask students to suggest more examples they’ve heard or read.

Main Activity (30 minutes):

Prefix Skit Time 

Objective:

To use roleplay and drama to help students grasp the meaning of prefix-based words.

Instructions:

  • Divide the class into groups of 3–4

  • Assign each group a prefix and give them 2–3 base/root words

  • Groups create a short skit (1–2 minutes) showing the meaning of the new word

  • They perform the skit without saying the actual word

  • The rest of the class guesses the word

  • After guessing, the group says the word and uses it in a sentence

Examples for skits:

  • A child looking sad: “She’s unhappy.”

  • Someone writing again after making a mistake: “He had to rewrite it.”

  • A student misplacing a toy: “He misplaced his ball.”

  • A person eating too much food: “He overeats every day!”

Wrap-Up Discussion:

  • Ask, “Which word did you like the most?”

  • “Was it easy to act the meaning?”

Follow up task (30 minutes):

Prefix Practice Worksheet 

Objective:

To reinforce prefix usage in writing and comprehension.

Part A: Fill in the blanks with correct prefixes

Examples:

1. ___kind → unkind

2. ___play → replay

3. ___connect → disconnect

4. ___place → misplace

5. ___heat → preheat

6. ___behave → misbehave

7. ___stop → nonstop

8. ___cook → overcook

Part B: Write 3 sentences using new words

Examples:

  • “We had to rewrite the homework.”

  • “He misbehaved during lunch.”

  • “They preheated the oven.”

Peer Sharing:

  • Students pair up and read their sentences to each other

  • Encourage giving one positive feedback to their partner

Review Questions/Assessment/Tasks (10 minutes):

  • “What is a prefix?”

  • “Can you give an example of a word with dis-?”

  • “What does re- mean?”

Expected Learning Outcome:

Knowledge building:

  • Understand and identify prefixes and how they change word meanings.

  • Recognize common prefixes in everyday language.

Skill Building:

  • Confidently use prefix words in writing and speaking.

  • Work collaboratively in groups.

  • Improve sentence construction and vocabulary application.
