Dijkstra's Algorithm

Dijkstra's algorithm finds the shortest path for a given problem. Dijkstra's algorithm can be used to find the shortest route between two cities. This algorithm is so powerful that it not only finds the shortest path from a chosen source to a given destination, it also finds all of the shortest paths from the...

Pseudocode Challenge

This activity, created by Pete Dring and originally published here, contains a resource which is accessed via the web browser (although it is just on the local machine). The web page once loaded contains 20 interactive ...

Fly by the Stars

Satellites and other spacecraft use star cameras to image space and to determine which direction they are pointing.

This resource, suitable for upper secondary school students, looks in detail at the night sky, examining objects and orbital motion within the solar system. Constellations and the stories...

Compose Tune

Sonic Pi is a programming environment that lets you create music and other sounds with code while learning programming concepts at the same time, is included with Raspbian (the Raspberry Pi OS), but it is also available as a free download for MacOS, Windows, and Linux:

This...

Happy Birthday

In this project, part of the HTML and CSS projects , you’ll be introduced to HTML & CSS by learning how to make your own customised birthday card.

Teachers and session leaders should access the ...

Starting from Scratch

Scratch is widely used in primary schools to teach children basic programming. This resource goes deeper, making use of the familiar Scratch environment to take students deeper into programming concepts such as:

  • Algorithm design
  • Parallel and sequential instructions
  • Event-driven...

Coded simulation of Bubble Sort

This presentation guides students through an explanation & coded simulation of Bubble Sort. Students can add to this later by adding another option for Merge Sort with the potential to then measure the time taken for each algorithm to form a basis to compare the time complexity of the two. A copy of the...

Flowcharts and Pseudocode

An introductory lesson, linking ideas from flowcharts to the use of pseudocode. The presentation may need some editing to remove school specific information. It contains a link to the "Friendship Algorithm" sequence from Big Bang Theory and a link to the description section for Algorithms and Pseudocode from BBC...

Introduction to Algorithms

This resource details a real-world algorithm which students are unlikely to have encountered previously. The Luhn Algorithm is one method for validating that the long number on a credit/debit card is a valid number (it doesn't check if the card is actually a credit/debit one, just that the number conforms to the...

Introduction to Pseudocode

This activity features detailed instructions for a lesson to introduce the concept of pseudocode, using fairly simple but accessible graphics. The students are required to devise instructions in order to move a cartoon character on a grid including being able to interact with its' environment by picking up bananas...
