Activities
- Activity 1: Introduction to Elapsed Time
- Activity 2: Calculating Elapsed Time
- Activity 3: Elapsed Time Word Problems
- Activity 4: Elapsed Time Practice
Start by discussing what elapsed time means and why it is important. Give examples of real-life situations where knowing elapsed time is useful, such as cooking, sports events, or planning activities.
Provide the student with different scenarios involving starting and ending times. Ask them to calculate the elapsed time in minutes. Encourage them to use a clock or watch to help visualize the time intervals.
Present word problems that require the student to calculate elapsed time. Make sure the problems involve various time intervals, such as minutes, hours, or a combination of both. Guide the student through the problem-solving process.
Give the student a set of practice problems to work on independently. Provide feedback and assistance as needed.
