              How to use this book






              This workbook provides questions for you to practise what you have

              learned in class. There is a unit to match each unit in your Learner’s Book.
              Each exercise is divided into three parts:


              •  Focus: these questions help you to master the basics

              •  Practice: these questions help you to become more confident
                 in using what you have learned

              •  Challenge: these questions will make you think more deeply.

              You might not need to work on all three parts. Your teacher will tell you

              which parts to do.

              You will also find these features:

                                                                bisect   diagonal
