Normalisation of floating point binary numbers

Normalisation of floating point binary numbers is usually a topic where students require practice. This pair of documents explain the technique and then provide a set of questions with answers for independent working.

Binary, decimal, hexadecimal conversion activity

Students always need practice in number system conversion. This resource gives them instant feedback and allows them to progress from conversion to binary addition. This would make an ideal homework activity. the file is a macro enabled worksheet and can be downloaded from the zip file.

 

Teaching TCP/IP

Using analogies to teach the topic of the TCP/IP networking is often a very useful strategy. This Computing at School community resource consist of three documents. The first provides a theory overview of the communication process. The second provides a range of links and activities, although some are aimed at...

CPU jigsaw

This activity allows students to construct a paper CPU using “jigsaw” pieces. They can also add notes to their jigsaw explaining the function of each component. Carrying out this activity allows students to relate sub components of the CPU to one another. For example, they will appreciate that level 1 cache memory...

Types of processor activities

This document contains a number of activities for students to carry out. They develop an instruction set for a fictional processor which forms a thought-provoking introduction to this topic. Encourage them to think about basic mathematical operations and how data values need to be manipulated within the CPU. This...

Programming languages - Harold the robot

In activity children simply give directions to a “robot” (either an adult or another child) and find out which instructions the robot is able to follow, and how their instructions are taken literally. It allows children to explore whether it is better to have a large complex set of instructions or a small...

Network protocols

In this activity students consider how different methods of communication operate successfully. By looking at rules and procedures in place, students are introduced to communication protocols. By working through a role-play scenario, pupils test their own protocol operating in an unreliable environment...

Databases unplugged

This report gives details of a series of computing lessons designed to relate fundamental concepts of database use and design to children in Primary and Secondary Education (ages of 6 to 16). The skills and concepts developed in these lessons begin at a very simple level but progress to cover abstract...

Modems unplugged - sound representation

All data on computers is stored and transmitted using the binary number system. When the binary digits need to be sent over the phone lines (which often happens in home internet connections), the digits are converted to sound and decoded at the other end using a modem. This activity uses audio coding similar...

Itching for more

Designed for students who have advanced through Scratch and are ready for additional challenge, this resource explores Build Your Own Blocks (BYOB) as a tool for learning modular programming using procedures. 

After examining, briefly, the history of the computer and the Turing Test as a measure of their...
