This book covers all the topics in construction that is tested for CSEC Mathematics. The basic concepts are introduced first and students need to work through these with the use of their geometric instruments. After students have mastered these basic concepts, there are problems that need the applications of two or more of these concepts. Finally, there are structured problems where students apply all their knowledge that was learnt in construction, to work through.This book is designed for anyone who has never done construction before. No previous knowledge was assumed, so forms 1, 2 and 3 students will benefit from this book. Repeater students will profit tremendously when they work through the contents of the book. Adults can also use the book if they want to develop new skills and knowledge. A tutor is not needed if someone wants to use the book independently. Teachers, who are giving crash courses, can use the book with their students and they will master this topic within a day or two depending on their level of attainment. I will advise students and Teachers to immediately do past paper questions on construction, as soon as they complete this book, because all the concepts will be fresh in their minds.
