Topic 2: Computational Thinking Recap Quiz

Which of the following is the correct description of abstraction?

• Removing unnecessary details to make the problem simpler

• Breaking the problem down into smaller, more manageable tasks

• Completing some steps in similar or repetitive ways

• The process of developing an algorithm for another person or system to follow

You have been asked to describe what your teacher looks like to a new student

You only have 30 seconds left of form time to do this! Which of the following features is the least necessary for this task?

• Their gender

• Their height

• The length of their hair

• The colour pen they use

Which of the following is usually used during abstraction to represent buildings on a map?

• Squares / rectangles

• Simpler versions of the building

• Photographs

Select all advantages of using abstraction

• Simplifies the problem

• Allows you to focus on essential details fist

• Ensures no mistakes can be made

Select all ways abstraction has been used in this example

• Colours to represent commands

• Blocks to represent text

• Picture of the flag to represent a command

• Colours to represent colours

Which of the following is the correct description of decomposition?

• Removing unnecessary details to make the problem simpler

• Breaking the problem down into smaller, more manageable tasks

• Completing some steps in similar or repetitive ways

• The process of developing an algorithm for another person or system to follow

Which form of computational thinking is being represented here?

• Decomposition

• Abstraction

Imagine you have been asked to create a Lego model

Which of the following would be an example of decomposition during this task?

• Completing each element of the model separately, then combining them at the end

• Focussing only on the most important elements of the model first

• Looking back at previous models for guidance

Select all advantages of using decomposition

• Breaks it own into smaller problems

• Each problem is more managable

• It can be worked on as a team

• Ensures no mistakes can be made

Imagine you only have 1 hour before you need to go to bed but you still have to finish all your homework for the next day of school

Select all examples of how decomposition could be used

• Split into individual lessons

• Prioritise by lessons you find mot difficult

• Work on it as a team with a family member / friend online

• Disregard anything that is important right now
