 | Full Description:
This book is designed to help students develop the various skills required to pass Key Skills Application of Number Level 2.
Each section is divided by curriculum reference and includes an explanation on ‘how to do it’, followed by exercises to consolidate learning. Key Skills Level 2 is tested using multiple choice answer sheets. However, the knowledge and skills required to answer these questions can only be developed through practice and application.
To gain a full pass at Level 2 a portfolio must be produced. All the explanations and exercises in this book support the building of the portfolio. Understanding and using mathematical information This book will enable you to read and understand straightforward mathematical information used for different purposes and independently select relevant information from given graphical, numerical and written material.
It will enable you to specify and describe a practical activity, problem or task using
mathematical information and language to make accurate observations and identify suitable calculations to achieve an appropriate outcome.
Calculating and manipulating mathematical information:
Generate results to a given level of accuracy using methods, measures and checking procedures appropriate to the specified purpose. Interpret results and communicate mathematical information. Present and explain results. |
