Lesson Plan: Networking II SS 3
LESSON PLAN: NETWORKING II
| Subject: | Digital Technologies |
| Class: | SSS 3 |
| Term: | First Term |
| Week: | 6 |
| Topic: | Networking II |
| Duration: | 80 Minutes (Double Period) |
| Subtopics: | IP addressing, IPv4 and IPv6, public and private IP addresses, subnet masks, CIDR notation, subnetting, and common network protocols and their functions. |
1. BEHAVIOURAL OBJECTIVES
By the end of the lesson, students should be able to:
- Define an IP address and state its functions.
- Differentiate between IPv4 and IPv6.
- Distinguish between public and private IP addresses.
- Explain subnet masks and CIDR notation.
- Define subnetting and state its advantages.
- Perform simple subnetting calculations.
- Identify common network protocols and explain their functions.
2. INSTRUCTIONAL / TEACHING AIDS
- Computer systems connected to a local network, where available.
- Router or network switch for demonstration.
- Whiteboard and markers.
- Charts showing IPv4 addresses and subnet masks.
- Prepared examples of IP addresses and network protocols.
- Projector or interactive display, where available.
3. PREVIOUS KNOWLEDGE / ENTRY BEHAVIOUR
Students have previously studied computer networking and the importance of connecting devices to share information. The teacher asks students how a computer communicates with another computer on a network and how a web browser accesses a website.
4. PRESENTATION STEPS
| STEP | TEACHER'S ACTIVITY | STUDENTS' ACTIVITY |
|---|---|---|
| Step 1: Introduction (5 minutes) | Reviews basic networking concepts and introduces IP addressing as a method of identifying network interfaces for communication. | Respond to questions and explain how computers communicate over a network. |
| Step 2: IP Addressing (15 minutes) | Explains IP addresses, IPv4, IPv6, public and private addresses, and static and dynamic addressing. Gives examples of IPv4 addresses. | Identify IPv4 addresses, distinguish between IPv4 and IPv6, and give examples of private addresses. |
| Step 3: Subnet Masks and CIDR (10 minutes) | Explains subnet masks and CIDR notation using examples such as 192.168.1.0/24. |
Identify the network prefix and host portion in simple IPv4 examples. |
| Step 4: Subnetting (20 minutes) | Defines subnetting and explains its advantages. Demonstrates how to calculate total addresses and usable host addresses in conventional /24 and /26 subnets. | Follow the worked examples and solve simple subnetting problems in their notebooks. |
| Step 5: Network Protocols (20 minutes) | Explains the functions of IP, TCP, UDP, HTTP, HTTPS, FTP, SMTP, POP3, IMAP, DNS and DHCP. | Match protocols with their functions and explain how they support network communication. |
| Step 6: Evaluation and Conclusion (10 minutes) | Asks questions on IP addressing, subnetting and protocols. Summarises the lesson and gives an assignment. | Answer evaluation questions, correct mistakes and record the assignment. |
5. EVALUATION QUESTIONS
- What is an IP address, and what are its functions?
- State three differences between IPv4 and IPv6.
- Differentiate between public and private IP addresses.
- What is subnetting, and why is it important?
- Calculate the total number of addresses and usable host addresses in a conventional IPv4 /26 subnet.
- Explain the functions of TCP, UDP, DNS and DHCP.
- Differentiate between HTTP and HTTPS.
6. ASSIGNMENT
- Explain the difference between static and dynamic IP addresses.
- List the three private IPv4 address ranges and give one example of a private IP address.
- A network is assigned
192.168.5.0/24. Calculate the subnet mask, total number of addresses and usable host addresses. - For
192.168.5.0/26, determine the network address, first usable address, last usable address and broadcast address. - Write the full meanings and functions of HTTP, HTTPS, FTP, SMTP, POP3, IMAP, DNS and DHCP.
7. TEACHER'S REFLECTION
After the lesson, the teacher should reflect on the following:
- Were students able to explain IP addressing and identify IPv4 addresses?
- Could students distinguish between public and private IP addresses?
- Were students able to perform basic subnetting calculations?
- Could students identify common network protocols and their functions?
- Which concepts require additional examples or practical revision?
