User:Ashishsainju lesson plan 7

Subject: Computer Science

Class: 8th grade

Duration:10 minutes

Period:2nd

Topic: Algorithm and Flowchart

Specific Objective:

At the end of the class, students will be able to understand

• the basic concepts of algorithms and flowcharts.
• how to create simple algorithms and represent them using flowcharts.

Materials:

• Whiteboard and markers

Introduction (2 minutes):

1. Begin with a brief discussion about problem-solving and the need for systematic steps to solve a problem.
2. Introduce the concept of algorithms as step-by-step instructions for solving a problem.

Main Content (5 minutes):

1.Explanation of Algorithms:

a. Define an algorithm as a set of well-defined, finite steps to solve a problem.

b. Use real-life examples to illustrate algorithms, such as a recipe for making a sandwich or steps to solve a math problem.

1. Introduction to Flowcharts: a. Explain that a flowchart is a visual representation of an algorithm. b. Present the basic symbols used in flowcharts, such as rectangles for processes, diamonds for decisions, and arrows for the flow of control.
2. Creating an Algorithm and Flowchart: a. Choose a simple problem (e.g., making a cup of tea) and collaboratively create an algorithm on the whiteboard. b. Translate the algorithm into a basic flowchart on the whiteboard, explaining each step.

Activity (2 minutes):

Divide students into small groups and provide them with a simple problem (e.g., brushing teeth). Ask each group to create an algorithm for the problem and represent it using a flowchart.

Conclusion (1 minute):

1.Discuss the activity results as a class, allowing each group to share their algorithm and flowchart.

2.Summarize the key points of the lesson: the definition of algorithms, the purpose of flowcharts, and the practical application of these concepts.

Assessment:

• Define Algorithm and Flowchart with suitable examples.
• Write Algorithm and Flowchart to sum up two positive integers.
