This activity explores the concepts of pattern recognition and problem decomposition. It illustrates these ideas using a popular children's book, "We're going on a bear hunt" by Michael Rosen.

Children are asked to apply their understanding by then creating functions using the Blockly editor on the Rapid...

This resource includes two lessons on sorting algorithms along with a piece of software to allow students to investigate how these algorithms function. The software itself is a simple game where students perform a given sorting algorithm on a set of data, and lose lives if they perform an incorrect step. The lesson...

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...

The Computing at School newsletter is published three times a year. It is full of practical ideas for teachers of computing in primary and secondary schools, with articles contributed by a number of CAS members. With input from teachers, academics, advisors and industry professionals, it provides a varied source of...

This resource contains a variety of activities and teacher resources to help students develop their problem solving skills, these are mostly through the use of unplugged activities which also encourage the development of skills associated with creating algorithms. The resources consist of teacher guides for each of...

A series of five lesson plans aimed at students with no knowledge of Python. In the description it is stated that depending on the students' level of ability these might be adapted to take up to eight lessons. The resource contains some discussion about how and why one might want to start using Python as their...

In this activity students explore why a water clock was the world's first programmable system. Programmable systems are by no means a modern invention. Many regard the first to be Ktesibios's water clock, which was invented approximately 2250 years ago.

The aim of this activity is that students apply what...

The twenty seven challenges contained in this booklet are designed to challenge and inspire students whilst helping them on their journey to becoming a ‘computational thinker’. The ideas contained in the booklet will also provide useful teacher stimulation when planning lessons.

Many of the challenges...

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...

The Magic of Computer Science II begins with an introduction to the resource, explaining the basic concepts used in the book. There follows descriptions of how to perform seven tricks with explanations of how the trick works and the computer science concepts illustrated in the tricks.

The joker in...

Our society is linked by many networks: telephone networks, utility supply networks, computer networks, and road networks. For a particular network there is usually some choice about where the roads, cables, or radio links can be placed. This resource explores the need to find ways of efficiently linking objects in...

When there are a lot of people using one resource, such as cars using roads, or messages getting through the Internet, there is the possibility of “deadlock”. A way of working cooperatively is needed to avoid this happening. The resource begins with instructions on how to play the orange game. The activity contains...

This activity shows how to accomplish a simple, but nevertheless seemingly impossible task -making a fair random choice by flipping a coin, between two people who don’t necessarily trust each other, and are connected only by a telephone. The resource begins with a detailed explanation of the activity and...

Many optimization problems involve situations where certain events cannot occur at the same time, or where certain members of a set of objects cannot be adjacent. For example, anyone who has tried to time-table classes or meetings will have encountered the problem of satisfying the constraints on all the people...

This edition of the Computing at School newsletter focuses on teaching computing in primary schools, and contains articles covering:

*Pedagogy of computing in primary schools

*National curriculum programme of study

*Game design in the primary classroom

*Primary – secondary transition...
