Computational Thinking for Problem Solving

What are the three key parts of computational thinking?

• Programming, flowcharts and pseudo code

• Abstraction, decomposition and algorithm

• Input, processing and output

• Patterns, shapes and numbers

What does the following flowchart symbol represent?

• A process

• Input / Output

• Start / End

• A sub-process

What does the following flowchart symbol represent?

• Process

• Input

• Start / End

• Sub-process

What does the following symbol represent in a flowchart?

• An input

• Start

• End

• A process

What is abstraction?

• A painting

• A programming language

• This means focusing on the important details and ignoring the irrelevant information

• Abstraction is the breaking down of a big problem into smaller parts.

What is computational thinking?

• It allows you to break down a large / complex problem into smaller parts.

• It is thinking like a robot

• It is being able to bake a cake.

• It is creating a coding solution to a problem.

What are the two main ways that we represent an algorithm?

• By drawing pictures

• Using flowcharts and pseudo code

• Using python and small basic

• Using Scratch and python

What does decomposition mean?

• focuses on the important information only, ignoring irrelevant detail

• Step by step instructions on solving a problem.

• Thinking like a computer

• This is the breaking down of a complex problem into smaller parts

What does the following flowchart symbol represent?

• Start of flowchart

• Input / Output

• End

• A process

What does the following flowchart symbol represent?

• A process

• An output

• A decision

• End
