What is it?
Computational thinking describes the processes and approaches we draw on when thinking about how a computer can help us to solve complex problems and create systems. We often draw on logical reasoning, algorithms, decomposition, abstraction, and patterns and generalisation when thinking computationally.
Australian Curriculum definition
A problem-solving method that involves various techniques and strategies that can be implemented by digital systems. Techniques and strategies may include organising data logically, breaking down problems into parts, defining abstract concepts and designing and using algorithms, patterns and models.

As computational technology advances, it is imperative that we educate young people and working adults to thrive in a computational world. In a computational world, what is important to know and know how to do?
The ‘chaos game’ is a way to see how patterns can result from certain random events. Use this program to run the ‘chaos game’, randomly moving the turtle to create a pattern (for more information, search 'chaos game’). Have students analyze or fill in or change parts of the pencil code program. Based on the original lessons developed by the Exploring Computational Thinking team at Google.
In this guide you will find 11 terms and definitions for Computational Thinking (CT) concepts. These concepts can be incorporated into existing lesson plans, projects and demonstrations in order to infuse CT into any disciplinary subject.
In this lesson, students are presented with the challenging problem of measuring a volume of water using containers that are not the exact measurement size. Students will decompose a complex problem into discrete steps, design an algorithm for solving the problem, and evaluate solution efficiencies and optimisation in a simulation.
Use this program to create an interactive chatbot who answers questions as if she is Lady Macbeth. Have students analyse, fill in or change parts of, or use the program to create their own variation and rendition of a character. This program could be used to further your understanding of how you could use Pencil Code in the classroom, as a demonstration or discussion with your students, or as a way to introduce various CT concepts, such as pattern recognition or abstraction, to your students by inviting them to extend the existing functionality of the program.
There are multiple factors to consider when travelling from one place to another. Unless the intent is to see specific points and landmarks, people are often interested in the most efficient way to get somewhere. In this lesson, students will experiment with different ways of creating a path between two points with algorithm design and generalising patterns. From the patterns, they will be able to generate an algorithm for efficiently travelling through cities in a region.
Language is one way to clearly and thoroughly describe the attributes and functions of ordinary everyday objects. In this lesson, students act like the inventor of an everyday object that does not yet exist. Students abstract the essential details, and describe what need would be fulfilled by the new object and how, specifically, it functions. They will then translate the description into a format appropriate for modelling the object in a computer by representing the data in an organised visual format. Pattern recognition will enable them to organise and generalise the description. Based on the original lessons developed by the Exploring Computational Thinking team at Google.
In many parts of the world, downloading images from the web can result in expensive data charges and greatly lengthen the time to load a webpage. Software engineers develop algorithms to reduce the size of images and text by looking at patterns in the data. Students will learn how the information in a pixel can be manipulated to change the image, and apply a bitmask filter to an image to remove some information and reduce the memory size of the file. Finally, students will modify the filter to find a balance between quality and small file size. Based on the original lessons developed by the Exploring Computational Thinking team at Google.
A cipher is a message that has been written in such a way (encoded) that it is unreadable by others. In this lesson, students will use mapping to encode a sentence. Students will work with a partner to create an algorithm that describes the encryption process. They will also examine encoded and decoded messages to recognise patterns to help decode messages and develop strategies to decompose the problem. Based on the original lessons developed by the Exploring Computational Thinking team at Google.

This lesson gives students the opportunity to practise the four arts of computational thinking (decomposition, pattern matching, abstraction and algorithms) in one cohesive activity.
Using the ‘odds and evens’ problem as a springboard, students construct interactive spreadsheets designed to address particular needs. This lesson also demonstrates an approach to programming known as rapid application development (RAD).
Students design a sequence of steps for others to follow. They convey their instructions to peers and evaluate the work of others to determine if the outcome was successful.
Students learn to code separate modules that perform discrete functions but collectively meet the needs of the solution. They select the most appropriate algorithm based on the type of problem.

This sequence provides a gentle introduction to the skill of decomposition by having students develop discrete modules that together serve a single need: a maths teacher asks for a program that can be used to demonstrate aspects of maths. This sequence can be used in conjunction with 'Comparing and selecting appropriate algorithms'.
