Previous Knowledge

Students have learned about programming and the importance of arranging instructions in a logical order.

Instructional Materials

• Computer system
• Flowchart symbols and charts
• Sample algorithms and pseudocode
• Whiteboard and markers
• Projector, where available

Reference Materials

• Digital Technologies lesson note on Basic Algorithms
• Teacher-prepared examples of algorithms, flowcharts, and pseudocode

Lesson Presentation

Stage/Time	Teacher's Activities	Students' Activities
1. Introduction 5 minutes	The teacher asks students to describe the steps involved in preparing tea or brushing their teeth. The teacher links their responses to the idea of algorithms.	Students describe familiar activities and arrange the steps in the correct order.
2. Meaning and Importance of Algorithms 15 minutes	The teacher defines an algorithm, explains its importance, and gives examples from everyday life and computer programming.	Students define an algorithm, give examples, and state its importance.
3. Problem-Solving Steps 10 minutes	The teacher explains how to identify a problem, analyse it, plan a solution, implement the solution, test it, and correct errors.	Students identify and explain the steps involved in solving a simple problem.
4. Pseudocode and Flowcharts 20 minutes	The teacher defines pseudocode and flowcharts, demonstrates pseudocode for adding two numbers, and explains the oval, rectangle, parallelogram, diamond, and flow-line symbols.	Students copy the example, identify the symbols, and explain the differences between pseudocode and flowcharts.
5. Practical Activity 20 minutes	The teacher guides students to write an algorithm and pseudocode for adding two numbers, then draw a simple flowchart representing the solution.	Students write the steps, prepare the pseudocode, draw the flowchart, and present their work for correction.
6. Evaluation and Conclusion 10 minutes	The teacher asks oral questions, corrects misconceptions, and summarises the lesson.	Students answer questions and summarise the main points.

Evaluation

1. What is an algorithm?
2. State three importance of algorithms.
3. What is pseudocode?
4. Explain the meaning of a flowchart.
5. State the functions of the oval, rectangle, and diamond flowchart symbols.
6. Write pseudocode for adding two numbers.

Assignment

1. Write an algorithm for calculating the area of a rectangle.
2. Write pseudocode for calculating the area of a rectangle using its length and width.
3. Draw a flowchart representing the calculation.

Teacher's Reflection

Were students able to define algorithms and represent simple solutions using pseudocode and flowcharts?
