Description

Help Students Prepare!

A Comprehensive Guide to The 11+ and Common Entrance Exams

The Teachitright Numerical Ability Workbook 2 provides a comprehensive set of questions to help students prepare for the key topics tested in both the 11+ and Common Entrance exams.

Classroom-tested in Teachitright centres, the questions are substantiated by the learn and develop sections which seek to enhance time management skills in the timed tests throughout the book.

As with Numerical Ability Workbook 1, this book drills down and tests core topics such as statistics, data handling and shape and space - as well as all-important attention to detail.

It offers an ideal resource for the CEM 11+ and Common Pre-Test exams, a detailed understanding of crucial question types, practice on ways to manage time efficiently, questions optimised for age and ability and explained answers and step-by-step hints and tips.

Introduction
This Numerical Ability Workbook 2 alongside Workbook 1 provides the perfect preparation for both 11+ and Common Entrance exams. This book contains data handling, shape and space and statistics. Workbook 1 contains the key topics working with numbers, equivalent values and algebraic calculations.
How to use this book
As this book is broken down into lessons that cover different topics, it can be used to focus on individual areas of development or to work through every mathematical topic.
Learn: An informative teaching section to help with the key points and techniques for that lesson topic. It includes worked examples.
Develop: Opportunity to practise short calculations based on the lesson topic to ensure key principles and techniques are fully understood.
Timed tests: Strategically placed progressive timed tests to help build confidence with worded problems and time management.
The answer section gives detailed explanations to aid revision. There is also a glossary on page 68 . It is important for the pupil to understand and learn keywords and phrases that are likely to appear in the exam.
In the back of the book is a marking chart and progress grid to help track your child s development throughout the topics and to highlight strengths and weaknesses.

SECTION 1: STATISTICS
Lesson 1: Ratio and Proportion
LEARN

In the first section of this book you will be learning about statistics, that is different ways of analysing data in large quantities. There are four lessons and the first one is on Ratio and Proportion.
Ratios
Ratios demonstrate the relationship between two numbers and how they compare to one another. Examples of ratios can be seen in many everyday situations, for instance when mixing up squash. If it states on the bottle 1 part squash to 4 parts water, it is important to add the correct quantities.
We often represent ratios as two numbers with a colon in between, for example 3:4
For example: The diagram below has a ratio of 3:4 and means 3 to every 4. For every 3 red squares there are 4 blue triangles. When something is shared in a ratio you first add up the numbers in the given ratio to find out how many equal parts you need. In the above ratio this would mean adding 3 + 4 together to equal 7. In the example about squash above, there are 5 parts in total (1 + 4).
So, if you see the following sign outside the cinema it can be represented as 1:2
1 FREE child cinema ticket to every 2 adult cinema tickets
To find an equivalent ratio you must multiply or divide both sides by the same number. Therefore, if we use the cinema ticket scenario again, if you had 4 adults going to watch the film you re entitled to 2 FREE child tickets.
2:4 = 2 free child tickets to every 4 adult tickets.
4:8 = 4 free child tickets to every 8 adult tickets.
Sometimes ratios can be shown with more than two numbers. For example, if we had a concrete mix containing cement, sand and stones, a typical mix might be in a ratio of 1:2:6. For every set quantity of cement, you require double the amount of sand and six times the amount of stones.
Proportion
A proportion of something is a way of describing a part of a whole . You can find the word proportion in everyday situations. For example, if you bake a cake, quantities in the recipe are increased in proportion if a bigger cake is needed.
Two quantities are in direct proportion when they increase or decrease in the same ratios. For example, if there are 4 boys to every 3 girls in a class, the proportion of 8 boys to every 6 girls would be the same. The two ratios are the same, 4:3 and 8:6 but the first is written in the simplest form.
An example of a proportion style question:
If 12 pencils cost 60p. How much would 15 pencils cost?
First, work out the cost of one pencil, which is 60 ÷ 12 = 5p. Then, to find the cost of 15 pencils, multiply 15 by 5. This equals 75p.
