Volume 2: Data Handling:
These exemplary presentations are ideal tools for those teaching GCSE Mathematics. They cover all the theory for Data Handling and, in addition, provide worked examples, summaries and introductory exercises to test students’ understanding - with solutions. Whilst aimed principally at whole class teaching, they can be used by individual students or small groups to help them when they have missed work or when they are revising.
There are 30 files. Where possible, real data has been used so that students see the relevance of the topics to everyday life. Text, diagrams and examples are animated to explain and enliven the work and teachers can control the speed at which the presentations run and pause whenever they wish. From time to time, the presentations ask students to share ideas so that they gain confidence.
work for the Foundation tier.
H: Topics which appear only in the Higher tier content.
Most of the foundation tier content, as given in the GCSE Mathematics specifications, is repeated for the higher tier. Even where this not so, the nature of the subject is such that exam questions at the higher tier could well include ideas and material from the foundation level. So, in writing the presentations, it has been assumed that all students taking the higher papers will study and revise all the foundation material.
The Contents file is the key to easy access to the presentations. The
titles have been hyperlinked to the files and colour has been used to group
For example, work on probability occurs at both tiers and the file titles are coloured blue in the contents.
H6 Probability and Independent Events
F16 Calculating Probabilities
H7 Tree Diagrams
F17 Probability – Theory
H8 Two-Way Tables and Probability
Since students sometimes experience difficulty handling fractions, many of the probability examples are worked using fractions and answers are cancelled to their lowest form.
Clip art images are used as follows:
Students should check the result on a calculator.
A summary of the key points in a form suitable for note taking.
Exercises that do not require a calculator. Some involve arithmetic that gives practice for non-calculator papers.
Exercises where a calculator is useful or essential.
Animations will not work correctly unless Powerpoint 2002, or later, is used.
