This sub-collection of resources from the Virtual Text Book collection contains three resources designed for use on an interactive whiteboard to aid the teaching and learning of a variety of topics in ‘Series'. Each resource is an interactive Excel worksheet to encourage teacher-student interaction. The topics...

This session introduces you to the use of binary digits to represent basic images and the key terms for capacity. During the session you will investigate 4-bit binary numbers and look at the patterns in the numbers.

1. Open Slides and read through slides 2 and 3 to get an understanding of the session that...

This session introduces you to converting denary or base 10 numbers to binary digits and back again. It consists of two files, a set of slides explaining how binary conversions work and a worksheet.

1. Read the slides in Slides - Binary Digits about binary digits. Make sure you are clear on how the values...

This is a short session looking at the structure of pixels in a digital image. It will help you understand how the number of bits used per pixel determines the number of colours that are available.

1. Open the Information document and read through the information about digital images. Look at how using...

This session explains how sound is converted from a continuous analogue sound that we hear in the real world and converts it into a digital format of 1s and 0s that can be used and played back by a computer. The session has a set of slides to read through and a worksheet.

1. Read slides 1 and 2 . This...

This session looks at how images and sound use compression to reduce their size when storing them or transferring them over the Internet or on devices to save space. In the session you will have a look at how an algorithm can be used to compress this data.

All the answers are to be written in the workbook....

The purpose of session 6 is to introduce you to how computers detect errors in data and where the error occurs. It will introduce you to the idea of parity bits and parity check to determine if the data has been corrupted. This session requires the use of a pack of cards or cards with a colour on one side.

This resource contains the second session of the Active Approaches to Level Three Applied Science, produced by the Science Learning Centres and the Nuffield Foundation, and concentrates on the issues of health and safety and risk assessments. The session identifies suitable practicals and includes activities.

The Midland Mathematical Experiment, in which a number of schools collaborated with the aim of developing a new approach to teaching mathematics in the Grammar School, developed a series of books to cover their ‘A’-level syllabus. Sets, Mappings, Relations and Operations is split into sections, each section...

This activity helps learners begin to consider some issues involved in setting up their own business by making an initial, outline, mathematical model of the costs involved in setting up a business. Learners are required to work in small groups to create a poster showing the factors they would take into account,...
