Material Required 1. Whiteboard and markers 2. Flashcards with prefixes and root/base words 3. Prefix rule chart 4. Worksheet with fill-in-the-blanks and sentence-writing 5. Props (optional) for theater skits (like books, food pics, toys)
Methodology 1. Interactive, activity-based learning 2. Group work and peer interaction 3. SEL integration: collaboration, empathy, self-confidence 4. Use of language in real-life context through drama and writing
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.
