Computational Thinking

What is the correct definition of an algorithm?

• An algorithm is a step by step instructions to solve a problem.
• An algorithm is a process of baking bread.
• An algorithm is a software used to compute numbers.
• An algorithm is the process of breaking problems.

Breaking a complex problem down into smaller problems and solving each one individually.

• Decomposition
• Abstraction
• Programming
• Algorithmic Thinking

Picking out the important bits of information from the problem, ignoring the specific details that don't matter.

• Decomposition
• Abstraction
• Programming
• Algorithmic Thinking

A logical way of getting from the problem to the solution. If the steps you take to solve a problem follow an algorithm then they can be reused and adapted to solve similar problems in the future.

Mike is posting an online advert on a forum to promote his band's upcoming tour. Abstraction?

• Other bands
• His age
• His parents names
• Date of Tour

Which of these is an example of decomposition?

• Breaking the problem of organising a cake sale into smaller parts, such as who will bake the cakes and when to hold the cake sale.
• Taking the problem of baking a cake and thinking about how we can make it the best cake possible.
• Looking at what different kinds of cake can be made.

Which of these would not be involved in decomposing a problem?

• Thinking about how the problem could be divided into smaller parts
• Working out who could help you solve a part of the problem
• Adding more parts to the problem so it becomes more complaex

What is abstraction?

• The process of filtering out unnecessary detail.
• The process of filtering out irrelevant characteristics
• The process of filtering out irrelevant characteristics and unnecessary detail.

To be able to draw cars, which one of the following characteristics is it necessary to know about?

• Who owns them
• Who sells them
• If they have wheels

Why do we need to think computationally?

• To help us program
• To help us solve complex problems more easily
• To help us to think like a computer
