6.3 Thinking Procedurally

• What is the main focus of computational thinking?

  Creating algorithms to solve problems
• What is abstraction in computational thinking?

  Removing unimportant details from a problem
• How would you model a garden in a program?

  Use a green mesh or image representation
• Why do users not need to know complex procedures for saving files?

  Because abstraction simplifies user interaction
• What components might a teacher consider when calculating grades?

  Number of classes, students, assessments
• What is the significance of identifying components of a solution?

  It helps match problem components with solutions
• What does procedural abstraction involve?

  Using procedures to execute sequences of instructions
• What types of data might be input parameters in a grade calculation?

  Integer, real/float, string, boolean
• Why is efficiency important in algorithms?

  It determines the algorithm's performance
• What is decomposition in problem-solving?

  Breaking a problem into smaller sub-problems
• What is top-down design?

  Breaking down a problem into major tasks
• What is the goal of top-down design?

  To structure a program into manageable tasks
• What are the advantages of decomposing a problem?

  Simpler testing and maintenance of subroutines
• What is a hierarchy chart?

  A diagram showing problem decomposition
• How do hierarchy charts represent problems?

  As a tree structure of subproblems
• Why is it important for sub-tasks to be easily solved?

  To ensure clarity and manageability in programming
