Even though computers are fast, there is a limit to how quickly they can solve problems. One way to speed things up is to use several computers to solve different parts of a problem. In this activity sorting networks are used to do several sorting comparisons at the same time. This resource begins with a discussion...

This activity for younger children introduces algorithms and algorithmic thinking. After first planning how to draw numbers using the simple commands available, children then program a BeeBot to create the shapes (BeeBots are a type of simple programmable rover). By watching and feeding back on each other's efforts...

This introduction to using the small programmable robot, the BeeBot, introduces children to creating simple programs. They learn the importance of sequences of accurate instructions, and test their sequences out using a 'fakebot' or paper-robot. Children are encouraged to debug and develop their sequences before...

For lower-primary children with some understanding of algorithms, this Barefoot Computing activity uses a basic robot (BeeBot) to show how algorithms are executed as stored programs on digital devices. Simple sequences of instructions are given to the BeeBot to 'write' numbers. These algorithms are represented by...

This archive document guides teachers introducing Logo to the computing classroom. While some sections may refer to outdated technologies, many of the techniques and learning outcomes remain relevant to users of any Logo platform. The activities begin with simple drawing using the turtle and pen, and progress...

The cs4fn magazine is a magazine on the fun side of all things to do with computer science. The authors write up computing research in a fun and accessible way that puts across their enthusiasm for the subject. Unplugged computing, computational thinking and practical applications of computers in many areas are...

When data is stored on a disk or transmitted from one computer to another, it is usually assumed that it doesn’t get changed in the process. But sometimes things go wrong and the data is changed accidentally. This activity uses a magic trick to show how to detect when data has been corrupted, and how to correct it...

This cross curricular activity includes science content from Year Four of the primary curriculum. It introduces programming and control, linked to the outside world through sensors - in this case, the computer's built-in microphone or a peripheral microphone. Programs are written using Scratch (online or offline)...

This collection includes resources for primary schoolchildren of all ages learning early computer programming. Using the Blockly drag-and-drop visual language, children program the movement of grocery vans around maps. The resources should be used with the ...

Following on from the Key Stage 1 and Key Stage 2 Blockly activities using Rapid Router, this teacher guide introduces Python textual programming. The difficulty of the algorithm challenges and the coding required is raised to new levels, but adequate support is provided in the guides. This resource makes use of...

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...

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...
