What is Elapsed Time?
Elapsed time is the amount of time that passes between two events.
Whether you're timing how long your homework takes or figuring out when your favorite show starts, understanding elapsed time helps you plan your day and solve real-world problems!
How to Calculate Elapsed Time
1️⃣ Identify the start time and end time
2️⃣ Count the hours first, then the minutes
3️⃣ Subtract the start time from the end time
Let's Practice Together!
Example 1: Movie Time
If a movie starts at 3:45 PM and ends at 5:30 PM, how long is the movie?
Let's break it down:
From 3:45 PM to 5:45 PM would be 2 hours, but the movie ends at 5:30 PM.
So we subtract 15 minutes: 2 hours - 15 minutes = 1 hour and 45 minutes!
🎬 Movie duration: 1 hour 45 minutes 🎬
Example 2: Bike Ride Challenge
Sarah started her bike ride at 9:15 AM and finished at 11:40 AM. How long did she ride?

Parent Tips 🌟
- Make it real: Have your child calculate elapsed time for daily activities like screen time, homework, or sports practice.
- Clock practice: Use an analog clock to help visualize time passing - this strengthens both elapsed time and clock-reading skills.
- Travel planning: Involve your child in calculating travel times for trips or outings to show real-world applications.
