Preface

This book is written to assist pupils in preparing for the Primary 3 Math examinations. There are a total of 8 specially crafted examination style papers. The main features of the papers are as follows.

1. Questions are modeled after examination papers set by top well known Singapore schools.

2. Questions are crafted to highlight common misconceptions in each of

the topics. This book comes with a multimedia CDROM. The CDROM contains detailed explanation of each question in each paper by our teacher. These lessons ensure pupils understand the methods behind solving each question. Outreach Book Alive series brings the “tuition teacher” to you at zero cost.
