Grade 4 Mathematics Module: Elapsed Time

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.

Good day to you! Do you know how to read time in minutes or seconds? Reading time is necessary for you to be able to find the length of time that an event occurred. This is called elapsed time. Elapsed time identifies how long you had been doing an activity like reading, cooking, browsing the internet, cleaning, etc. You will also learn to estimate elapsed time in minutes and seconds which is an essential skill in telling time. Real-life problems are also presented for you to know how important elapsed time is.

Finding elapsed time is different from just adding or subtracting numbers because in here, hours, minutes and seconds are all different units. So, GOODLUCK! Enjoy this module and remember that “Time is gold!”

After going through this module, you are expected to:

1. find the elapsed time in minutes and seconds;

2. estimate the duration of time in minutes; and

3. solve problems involving elapsed time.
