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 Material
Whiteboard and markers.
Chart paper and markers.
Individual sheets of paper and pencils for each student.
Symbol of flow chart
Introduction
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:
Introduce the basic components of a flowchart:
Oval: Represents the start or end of a process.
Rectangle: Represents a process or task.
Diamond: Represents a decision point (yes/no question).
Parallelogram: Represents input or output operations.
Arrow: Represents the flow or direction of the process.
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:
Ask students to create a flowchart for a process of calculate volume of cube in copy.
Write an algorithm and draw a flowchart to print natural number from 1 to 10 and find their sum.
Emphasize the use of different shapes for different components.
Walk around the class to provide assistance and guidance.
Conclusion:
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.
