Lesson 1.7 Top Down Design and Decomposition in Karel

Description

In this lesson, students learn top down design and decomposition as the processes of breaking big problems into smaller, manageable pieces. The functions improve the readability of the code and avoid repeated code.

Objective

Students will be able to:

  • Break a large problem down into smaller, simpler problems
  • Write functions that solve the simpler problems, and use them as building blocks to solve the larger problem
  • Compare programs and identify good vs. poor decomposition
