HT4 - Y8 Computational Thinking Quiz

What is computational thinking?

• A set of step-by-step instructions to solve a problem

• A way of visually representing an algorithm

• A method to take a complex problem, understand it, and develop solutions

• A programming language

Which of the following is NOT one of the 4 key techniques to computational thinking?

What is the purpose of decomposition in computational thinking?

• To create step by step instructions

• To focus on what's important and ignore the unnecessary

• To break up a problem into smaller parts to make it easier to solve

• To look for similarities and trends

What does abstraction help with in computational thinking?

• Creating a visual representation of an algorithm

• Focusing on the important parts and ignoring what is unnecessary

• Breaking up a problem into smaller parts

• Writing code in a programming language

What is an algorithm?

• To compile and execute an algorithm

• To recognize patterns within the algorithm

What does each shape in a flowchart represent?

• A random part of the algorithm

• A large portion of the algorithm

• One small part of the whole algorithm

• The entire algorithm

What is the purpose of arrows in a flowchart?
