This Self-Learning Module (SLM) is prepared so that you, our dear learners, can continue your studies and learn while at home. Activities, questions, directions, exercises, and discussions are carefully stated for you to understand each lesson.
Each SLM is composed of different parts. Each part shall guide you step-by-step as you discover and understand the lesson prepared for you.
Pre-tests are provided to measure your prior knowledge on lessons in each SLM. This will tell you if you need to proceed on completing this module or if you need to ask your facilitator or your teacher’s assistance for better understanding of the lesson. At the end of each module, you need to answer the post-test to self-check your learning. Answer keys are provided for each activity and test. We trust that you will be honest in using these.
Please use this module with care. Do not put unnecessary marks on any part of this SLM. Use a separate sheet of paper in answering the exercises and tests. And read the instructions carefully before performing each task.
Hi, Mathletes! The International Meridian Conference was held in October 1884, in Washington, D.C. to determine a prime meridian for international use. The conference discussed the choice of a meridian to be employed as a common zero of longitude and as the standard of time reckoning throughout the world. It resulted in the recommendation of the Greenwich Meridian as the international standard for zero degrees longitude. That’s when the different time zones started.
In this module you are going to learn how to calculate time in different world time zones in relation to the Philippines. To do this, we need to use the world time zone map to easily understand the time differences.
When you finish this module, you will be able to:
- perform calculations with time in different time zones in relation to the Philippines,
- calculate 12-hour and 24-hour clock times and conversions between time zones in relation to the Philippines, and
- appreciate the importance of the world time zone map for us to easily understand the time difference.
Before you start exploring the lesson, let us check if you are familiar with calculating time in different world time zones.
