**THE NATIONAL CURRICULUM**

The subject of Maths is an integral lesson within the national curriculum. Students should be able to understand the key concepts and different mathematical formula in order to enhance their knowledge and increase their cognitive ability.
By achieving a strong level of understanding, students are able to convey their mathematical knowledge in a range of other subjects including science, computing and geography.
The fundamental aims of the Maths subject include:
- Applying arithmetic to solve problems;
- Understanding the difference between accuracy and estimation;
- Expressing arithmetic using algebraic equations and formula;
- Learning how to carefully lay out sets of data using graphs and charts;
- Understanding averages in terms of mean, mode, median and range;
- Improving on their basic mathematical skills, before advancing on to more technical and challenging mathematical concepts;
- Improving children’s confidence in their mathematical abilities, allowing them to grasp different topics of maths and how they can apply these techniques to their work.

In Key Stage 3, maths is broken down into several modules:

- Numbers and Calculations;
- Ratio, Proportion and Rates of Change;
- Geometry and Measures;
- Working with Algebra;
- Probability and Statistics.

**PROBABILITY AND STATISTICS**

Key Stage 3 Maths Is Easy – Probability and Statistics is a new revision tool for the current national curriculum.

With this guide comes great preparation for children aged 11-14. Packed full of practice questions, this guide will no doubt improve your child’s learning and ultimately increase their classroom learning.

This guide is packed full of detailed information, ample sample questions and top tips and advice regarding the Maths KS3 curriculum.

## SAMPLE KS3 MATHS QUESTIONS

**Question 1**a) Unlikely b) Likely c) Impossible

**Question 2**a) 40 b) 4 c) 7 and 7

**Question 3**a) b) c) The line of best fit shows a weak positive correlation between the data. Generally, when someone scores highly in English, they also score highly in Maths. Although, this is not always the case, many of the results do show a weak relationship between test scores.

**Question 4**a) 4 and 5 cars (Both these categories have the value 24.) b) 6 (Highest value subtract the lowest number of cars = 6 – 0 = 0) c) 4 (Frequency total is 82. The middle number is 41. This number would occur in the fourth category (number of cars 4). So therefore the median is 4.)

All it takes is a little bit of time and practice!
