Session 20: Prefixes

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?”
