Divide and conquer

This activity provides a mathematical problem that is solved in a simple way. It relates to the way algorithms are used in search engines and links to problem solving in maths. The context is that of Santa trying to find his socks in one of 1024 boxes, which a...

Introduction to computational thinking and the Internet of Things

This one-hour lesson examines the design of IoT algorithms, considering how individual devices execute algorithms as code, allowing them to work together. The key aims are to develop computational thinking while raising awareness of the potential for future careers and enterprise.

The lesson starts with the...

Designing robots for small spaces

Inspired by the Born to Engineer video from Mathew Holloway, this resource uses the Crumble controller, setting students a design challenge that sees them create their own umbilical controlled buggy that can navigate small spaces. Although specific to the Crumble controller, this resource could be used as a design...

A positive human future

This resource was designed by The Economist Educational Foundation to support PA’s Raspberry Pi competition 2020. However, it can also be used by schools that are not taking part in the competition as a great subject to stimulate creative thinking and debate about real world issues, from...

Selecting Search Results

This Barefoot Computing primary school resource helps children to Understand how search engines work. By acting as a ‘web crawler’ and collecting information across a small selection of web pages, they learn what in data is indexed by search engines and how this is used when a search query is received. As well as...

Variables Unplugged

This activity away from the computer is from the Barefoot Computing project. It is intended to provide a theoretical understanding of why and how variables are used in computer programming, using the example of score-keeping in a classroom quiz. Involving several volunteers from the group, the activity uses...

Scratch Maths Quiz Variables

This Barefoot Computing resource builds on the ‘Maths quiz with selection’ learning activities which should be undertaken first.

It involves improving an existing Scratch maths quiz and adding score-keeping using variables – a quiz Scratch file is provided for students who do not have access to one they made...

Where Would You Photograph? (7-11)

In this activity children take on the role of Earth observation scientists submitting a request for an image they would like for their research. This gives them the opportunity to consider the possibilities of pictures taken from orbit (and the limitations) and to write scientifically for a specific audience. It...

Where Would You Photograph? (11-14)

In this activity students take on the role of Earth observation scientists submitting a request for an image they would like for their research. This gives them the opportunity to consider the possibilities of pictures taken from orbit (and the limitations) and to write scientifically for a specific audience. It...

Watching a Glacier (11-14)

This brief activity uses false-colour images of the Columbia glacier to introduce the idea of using sequences of satellite images to monitor change and focuses on the selection of appropriate data for an investigation.
