User:Ram baduwal Real Teaching Lesson Plan 9

Subject: Computer science

Topic: Flowchart And Its Components

Time: 45 minutes

Number of student: 25

Class: 9

Period: 5th

School: Shree Okhreni Secondary School

Specific Objectives:

1. Understand the concept of a flowchart and its importance in algorithm design.
2. Identify and explain the components of a flowchart.
3. Create simple flowcharts to represent basic algorithms.

Teaching Aids:

1. Whiteboard and markers]
2. Projector or screen for presentations
3. Handouts with examples of flowcharts

Classroom Activities:(35 min )

• Begin with a brief discussion on the importance of visual representation in problem-solving.
• Explain that a flowchart is a graphical representation of a process or algorithm.
• Discuss real-life examples where visual representation is useful, like cooking recipes or assembly instructions.

Definition:

Discuss the definition of a flowchart - a diagrammatic representation that illustrates a solution model to a given problem.

Purpose:

Explain that flowcharts help break down complex processes into smaller, more manageable steps.

Advantages:

Discuss the advantages of using flowcharts, such as clarity, simplicity, and ease of understanding.

Components of a Flowchart

Start and End Symbols:

Explain the oval shape used to represent the start and end of a process.

Process Symbols:

Discuss rectangles for representing processes or actions.

Decision Symbols:

Explain the diamond shape for representing decision points with yes/no branches.

Input/Output Symbols:

Discuss parallelograms for representing input or output operations.

Flow Arrows:

Emphasize the use of arrows to indicate the flow or sequence of steps.

Activity - Creating a Simple Flowchart

• Provide a simple algorithm and ask students to create a flowchart on their own.
• Encourage them to use the symbols discussed earlier.
• Walk around the class to provide assistance and answer questions.

Examples and Discussion

• Display pre-made flowcharts on the projector for common algorithms. Discuss each example, emphasizing the use of symbols and the flow of the process.

Conclusion:(5min)

• Recap the key points discussed during the lesson.
• Emphasize the importance of flowcharts in problem-solving.
• Assign homework: Ask students to create a flowchart for a given algorithm as practice.

Evaluation:(5min)

• Given a simple algorithm, create a flowchart using appropriate symbols.
