The video tutorial teaches the timeline strategy for calculating elapsed time. It uses a practical example of determining the time between school ending at 2:45 PM and dinner at 6:30 PM. The process involves breaking down the time into manageable parts: adding minutes to reach the next hour, adding full hours, and then adding remaining minutes. The total elapsed time is calculated as 3 hours and 45 minutes.

What is the main focus of the timeline strategy discussed in the video?

• Solving algebraic equations

• Learning multiplication

• Understanding fractions

• Calculating elapsed time

At what time does the student leave school?

• 2:30 PM

• 3:00 PM

• 2:45 PM

• 6:30 PM

What time is dinner scheduled for?

• 5:00 PM

• 7:00 PM

• 6:00 PM

• 6:30 PM

How many minutes are added to reach the next full hour after school ends?

• 20 minutes

• 15 minutes

• 10 minutes

• 30 minutes

What is the next full hour after adding 15 minutes to 2:45 PM?

• 3:30 PM

• 3:00 PM

• 2:50 PM

• 3:15 PM

What is the first step in calculating elapsed time using the timeline strategy?

• Dividing the minutes

• Multiplying the hours

• Adding minutes to reach the next hour

• Subtracting hours

What is the purpose of adding 15 minutes initially?

• To divide the time equally

• To subtract from the total

• To calculate the total time

• To reach the next full hour

How many hours are added to reach 6:00 PM from 3:00 PM?

• 2 hours

• 5 hours

• 3 hours

• 4 hours

What is the total time from 3:00 PM to 6:00 PM?

• 2 hours

• 3 hours

• 4 hours

• 5 hours

Why is it easier to add hours after reaching a full hour?

• Because it simplifies the calculation

• Because it adds more minutes

• Because it reduces the total time

• Because it makes the time shorter
