LESSON DEVELOPMENT

Stage/Step (Time)	Teacher's Activities	Student's Activities	Learning Points
Introduction 5 MINUTES	Welcomes learners, revises Week 1 (Review of Networks, the Internet and Digital Safety) with two quick oral questions, and asks what they already know about Internet and Web Technologies. Elicits responses and writes the topic on the board.	Recall the previous lesson and share what they already know about Internet and Web Technologies.	Connecting prior knowledge to Internet and Web Technologies.
Step 1 6 MINUTES	Covers Starter Scenario: Chidi in Abuja sends a short birthday message to his cousin Amara in Lagos at exactly 9 o'clock in the morning. The message arrives on Amara's phone within one second, even though Lagos is over 600 kilometres away.

It is not owned by one person or one company.	Listen, take notes and answer oral questions on "Starter Scenario" and related points.	Understanding: Starter Scenario; The Internet and ISPs.
Step 2 6 MINUTES	Covers IP Addresses: Every device that connects to the internet is assigned a unique number called an IP address. IP stands for Internet Protocol. Covers URLs and the World Wide Web: A URL, which stands for Uniform Resource Locator, is the address of a specific page or file on the internet. Every web page, image, video and document online has its own unique URL.	Copy the key points, give examples from school and everyday life, and ask questions on "IP Addresses" and related points.	Understanding: IP Addresses; URLs and the World Wide Web.
Step 3 6 MINUTES	Covers Web Browsers: A web browser is software that lets you access, retrieve and display content from the World Wide Web.

Understanding: Search Engines and Safe Searching.
Practical Work 6 MINUTES	Guides learners through the practical work: (i) Write the parts of the URL www.school.edu.ng/subjects/ict and explain each part. (ii) Name four web browsers and state one feature of each. (iii) Describe the three steps a search engine follows: crawling, indexing and ranking. Moves round the class to check progress and correct unsafe or careless use.	Carry out the practical tasks individually or in pairs and record what they did in their notebooks.	Applying the lesson through hands-on practice.
Evaluation 3 MINUTES	Asks learners to: i. Explain what the internet is and the part an ISP plays. ii. Describe IP addresses, URLs and the World Wide Web. iii. Compare common web browsers and explain how a search engine works. iv. Judge the trustworthiness of online information and search safely.	Respond verbally and in writing to the evaluation questions.	Assessment and consolidation of the lesson content.
Conclusion 2 MINUTES	Recaps the main points: starter Scenario, the Internet and ISPs, iP Addresses, uRLs and the World Wide Web, web Browsers. Links them to the assignment and previews Week 3: Computer Networks.	Listen, ask questions and copy the assignment.	Reinforcement of key concepts and a preview of the next lesson.
