Elapsed Time Examples for 3rd Graders

📚 Quick Study Guide

• ⏱️ Elapsed time is the amount of time that passes from the start of an event to the end.
• 📅 To calculate elapsed time, you need to know the start time and the end time.
• ➕ You can use a number line, a clock, or subtraction to find the elapsed time.
• 🔢 Remember that there are 60 minutes in an hour!
• 💡 When subtracting time, if the minutes in the start time are more than the minutes in the end time, you may need to borrow an hour (60 minutes).
• ✍️ Example: If something starts at 2:00 PM and ends at 3:30 PM, the elapsed time is 1 hour and 30 minutes.
