Patterns Unplugged Activity

This short unplugged activity, away from computers, introduces pattern recognition using familiar objects. Children are asked to analyse groups of objects (cats, cars and so on) to identify features common to all of them. Exceptions to the 'rules' are discussed, and parallels with writing computer programs are...

Bug in the water cycle

A set of simple scratch ‘debugging’ activities that children can use to apply their understanding of programs and codes.  Children are shown a series of faulty programs which are based around the water cycle.  They are then supported to use logical reasoning to locate and fix the bugs within them.  Notes for...

Dinosaur Fossil Animation Sequence Activity

This Barefoot Computing animation project for primary school computing teaches the concept of sequencing within programs. Children use costumes and a range of commands in Scratch to produce purposeful multimedia. They are encouraged to debug and improve the program, and can extend the challenge by recording sound...

Pizza Pickle Scratch Debugging Activity

This Barefoot Computing activity challenges lower-primary children to debug simple Scratch programs that assemble pizzas on-screen. A simple four-step process for systematic debugging is demonstrated.

Using logical reasoning and learning-by-doing, children predict the outcomes of algorithms that contain...

2D Shape Drawings Activity: an Introduction to Debugging Algorithms

This Barefoot Computing activity for upper primary goes deeper into the concept of algorithms, using logical reasoning and debugging to find errors and to improve accuracy and efficiency. By following instructions, children create diagrams constructed from simple shapes. They are asked to identify errors in the...

Abstraction Unplugged

This short activity for primary school computing uses art to introduce the concept of abstraction. During a ‘guess what’ game the children are asked to represent a word on a card using drawing or modelling – in doing so they unconsciously concentrate on just the most important aspects of the idea they are...

Bee-Bots 1,2,3 Programming Activity

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...

Patterns Unplugged: Reusing Recipes Activity

This 'unplugged' activity introduces pattern recognition and the idea that algorithms can be repurposed. Cooking recipes are analysed to find parts that are common to more than one. Reusable parts are then borrowed to create new recipes which the children share with the class. Additional teacher guidance is given,...

Logical Reasoning Activity

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...

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...
