Simplify the introduction to calculating elapsed time with our Elapsed Time Lesson Plan, which provides practical activities for student to understand adding and subtracting minutes and hours to determine elapsed time. Solidify understanding as students convert their age in years to months, days, hours and minutes, as well as analytical skills as student order themselves from youngest to oldest.
Sample Classroom Procedure / Teacher Instruction
- Ask: What is time? Does time seem to move fast or slow sometimes? Why do you think that happens? (The questions are to motivate students to think about time.)
- Allow for responses and discussion. Ask students how much time has passed since yesterday at 4:00 PM (or a different time). Ask students when it might be important to track the amount of time that has passed by or elapsed. (Exams, cooking, racing, etc.)
- Allow for responses. Introduce elapsed time.
- Distribute Elapsed Time content pages. Read and review the information with the students. The method used to determine elapsed time may vary from student to student. Use the additional resources to enhance understanding.
- Distribute Activity page. Read and review the instructions. Distribute supplies, fasteners, cardboard, etc. for students to create analog clock. Students’ use of the clock will help them better see and understand the passage of time, elapsed time. (Be sure students move the hour’s hand every 60 minutes.)
- Give students sufficient time to complete the activity and manipulate the clocks. When completed, students will exchange their responses with each other to check for accuracy. Circulate through the room to check for understanding and discrepancies.
- Distribute Practice page. Check and review the students’ responses.
- Distribute the Homework page. The next day, check and review the students’ responses. Allow volunteers to share their age in years, months, days, hours, and minutes. Identify the oldest/youngest in the classroom.
- In closing, ask: What are the advantages and disadvantages of a digital clock and an analog clock? (An explanation of an analog clock may be necessary during the activity.)
- Allow for responses and discussion.
