User:Saroj Neupane Lesson Plan 2

Subject: Computer Science

Class:9

Time:10 Minutes

Number of Students: 16

Unit:4

Topic: Flowchart and Its Components

Period: 7th

School: ABC School

Specific Objectives

• Students will able to understand the components of a flowchart and be able to create a simple flowchart with emphasis on using different shapes for various operations.

Teaching Aids

• Whiteboard and markers or a blackboard and chalk.
• Chart paper and markers.
• Individual sheets of paper and pencils for each student.

Introduction (2 minutes):

• Start by asking students if they have heard of flowcharts and if they know their purpose.
• Briefly explain that flowcharts are visual representations of processes or algorithms.
• A flowchart is a type of diagram that represents a workflow or process.
• A flowchart can also be defined as a diagrammatic representation of an algorithm, a step-by-step approach to solving a task.
• The flowchart shows the steps as boxes of various kinds, and their order by connecting the boxes with arrows.

Basic Components (2 minutes):

Flow Chart

• Introduce the basic components of a flowchart:

1. Oval: Represents the start or end of a process.
2. Rectangle: Represents a process or task.
3. Diamond: Represents a decision point (yes/no question).
4. Parallelogram: Represents input or output operations.
5. Arrow: Represents the flow or direction of the process.

Activity - Creating a Simple Flowchart (3 minutes):

• Choose a simple process (e.g., Calculate area of rectangle) and draw a flowchart on the whiteboard, incorporating all the components.
• Encourage students to ask questions and discuss the purpose of each shape.
• Have students practice drawing the flowchart on their individual sheets, focusing on using the correct shapes for each component.

Hands-On Practice (2 minutes):

• Ask students to create a flowchart for a process of calculate volume of cube in copy.
• Emphasize the use of different shapes for different components.
• Walk around the class to provide assistance and guidance.

Conclusion (1 minute)

• Ask a few students to share their flowcharts with the class, pointing out the different components used.
• Summarize the key components: ovals for the start/end, rectangles for processes, diamonds for decisions, parallelograms for input/output, and arrows for the flow.
• Emphasize the importance of using flowcharts as a visual tool for understanding and planning processes.

Assessment

• Check the flowcharts from the students copy.
• Assess the flowcharts based on the correct use of components (ovals, rectangles, diamonds, parallelograms, and arrows) and the logical representation of the chosen process.
