Lesson Plan for Primary 4 - Information Communication Technology - Computer Memory

### Lesson Plan: Introduction to Computer Memory **Class Level:** Primary 4 **Subject:** Information Communication Technology (ICT) **Topic:** Computer Memory **Duration:** 45 minutes #### Objectives: - Students will understand what computer memory is and why it is important. - Students will be able to differentiate between RAM (Random Access Memory) and ROM (Read-Only Memory). - Students will be able to explain the basic functions of RAM and ROM. #### Materials Needed: - Whiteboard and markers - Projector and computer for a short presentation - Printed handouts with basic information and simple graphics - Flashcards with key terms - A computer to demonstrate practical examples (if available) #### Lesson Structure: **1. Introduction (5 minutes):** - Greet the students and briefly review the previous lesson. - Introduce today’s topic: “Computer Memory.” - Explain the lesson objectives so students know what to expect. **2. Explanation Phase (10 minutes):** - **What is Computer Memory?** - Explain that computer memory is like a brain that stores information. - Introduce the two main types: RAM and ROM. - **RAM (Random Access Memory):** - Describe RAM as a type of memory that helps the computer work quickly. - Explain it is temporary storage that gets cleared when the computer is turned off. - **ROM (Read-Only Memory):** - Describe ROM as a type of memory where important instructions are stored. - Explain that ROM cannot be changed easily and stays the same even when the computer is turned off. **3. Interactive Demonstration (15 minutes):** - Use the projector to show a diagram highlighting where RAM and ROM are located in a computer. - Display a short animation or video that shows how RAM and ROM work. - If available, demonstrate on a real computer how RAM helps in opening applications quickly, and explain the role of ROM in starting up the computer. **4. Group Activity (10 minutes):** - Divide the class into small groups and give each group flashcards with key terms (RAM, ROM, Temporary, Permanent, Fast, Slow, etc.). - Ask the groups to match the key terms with the correct explanations and memory types. - Walk around the classroom to assist and address any questions. **5. Recap and Questions (5 minutes):** - Summarize the key points of the lesson using the whiteboard. - Ask students some recap questions to check their understanding: 1. What is the difference between RAM and ROM? 2. What happens to the information in RAM when the computer is turned off? 3. Why do we need ROM in a computer? **6. Homework Assignment:** - Hand out a simple worksheet with short questions summarizing the lesson. - Ask students to draw their own diagram of a computer showing where RAM and ROM are located. #### Assessment: - Monitor group activities to ensure comprehension. - Collect and review the worksheets to assess individual understanding. - Conduct a brief quiz in the next lesson to reinforce and evaluate retention. #### Closing: - Praise the students for their participation and enthusiasm. - Encourage them to think about how memory functions in their own computers or devices at home. - Briefly introduce what the next lesson will cover to maintain interest. ### Note to Teacher: - Be prepared with additional simplified examples and analogies if students need further clarification. - Engage with students by asking them to share any personal experiences with computer issues or speed to connect theory with practice.
