### 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.
