Pen Pal Book 3 is the last in the three-level series whose aim is to improve Writing, Speaking and Listening skills for students in A, B and C class. This book is designed to be used in conjunction with students' coursebooks. Each unit can be covered in three half-hour sessions, making a total of approximately 14 teaching hours.

The units are graded in difficulty, although students will meet only those structures familiar to them from their coursebooks. The topics in each unit have been chosen with this grammar in mind to enable students to write and talk about themes familiar to them. Speaking and Listening tasks are included to consolidate theme vocabulary.
