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...

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 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 computing resource for primary schools introduces the concept of decomposition through dance. Using combinations of hand-jive, clapping or tutting, the lesson demonstrates how complex sequences of instructions (algorithms) can be broken down into smaller chunks. The children are challenged to look for patterns...

This activity combines computing and maths to look at algorithms. Children are challenged to solve missing number problems in number sequences, using logical reasoning. Additional challenges are then presented, and children are asked to share not just the answer, but the approach they took to solving the problem...

This Barefoot Computing resource for upper-primary computing lessons uses the creation of a Scratch maths quiz as a basis for learning about algorithms using selection.

Children are asked to create an algorithm that...

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...

A cross-curricular programming activity, using loops in Scratch to draw patterns. Learners first design an algorithm to draw a simple 2D shape, and then use the 'repeat' block to generate artwork. It is advised that children have some prior experience of programming in Scratch. Experimentation and debugging is...

This resource contains a series of card tricks. Each trick is presented in two parts. In the first part enough detail is given so that the trick can be performed. A description of the desired effect is given followed by an explanation of the mechanics of the trick – actually what is done to ensure the trick works...

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...

This engineering activity, suitable for children in computing lessons, looks at the basics of flowchart construction. Simple examples, such as the decisions made by a dog chasing a stick, are used to make flowchart representation of algorithms accessible to younger children. A simple design activity requires...
