# Session 20: Prefixes
**Session Title** **Prefixes – Understanding and Implementation**
Objective - Understand what a prefix is and how it changes the meaning of a word. - Learn and identify common prefixes: un-, re-, dis-, mis-, pre-, non-, over- - Practice using prefix-based words in speech, writing, and performance. - Encourage communication, creativity, and confidence through interactive activities.
Topics/Concept - A prefix is a group of letters added to the beginning of a word to change its meaning. - Common Prefixes and Examples: - un-: unhappy, unfair, untidy - re-: redo, replay, rewrite - dis-: dislike, disconnect, disappear - mis-: misbehave, misplace, misunderstand - pre-: preview, preheat, preschool - non-: nonfiction, nonstop, nonliving - over-: overeat, overcook, overuse
Material Required - Whiteboard and markers - Flashcards with prefixes and root/base words - Prefix rule chart - Worksheet with fill-in-the-blanks and sentence-writing - Props (optional) for theater skits (like books, food pics, toys)
Methodology - Interactive, activity-based learning - Group work and peer interaction - SEL integration: collaboration, empathy, self-confidence - 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.
