Breaking Down Problems: The Art of Decomposition

YEAR 3

Learning Objective

At the end of the lesson, you will understand decomposition and use it to solve problems by breaking them into smaller steps.

What do you already know about breaking down problems?

What is Decomposition?

Decomposition is breaking a big problem into smaller, manageable parts. It's like dividing a large task into easy pieces.

Real-Life Examples

Cooking a meal: Break down into steps like gathering ingredients,

chopping,

cooking, and

serving.

Decomposition in Computing

In computing, decomposition helps programmers break tasks into smaller functions or modules.

Breaking Tasks into Steps

Identify the main task. List steps to complete it. Arrange steps logically to solve the problem.

Interactive Activity

Work with a partner. Choose a task and decompose it into smaller steps. Share your steps with the class.

Class Discussion

Discuss how decomposition helps solve problems. Share different approaches and learn from each other.

Review and Reflect

Review the key points. Reflect on how decomposition can be used in daily life and future learning.
