Elapsed Time Problem Solving

The video tutorial focuses on teaching how to find the end time when given a start time and elapsed time within the same hour. It introduces key vocabulary such as start time, elapsed time, and end time, and uses a timeline to visualize these concepts. The lesson progresses through three levels of questions: Level 1 involves digital clocks, Level 2 uses analog clocks, and Level 3 tackles word problems. The tutorial emphasizes using a timeline and the 'Hills and Mountains' strategy to solve elapsed time problems effectively.

What is the term used to describe the time when an event begins?

• End time

• Elapsed time

• Start time

• Duration

In the dinner-making example, how many total minutes did it take to prepare and bake the dinner?

• 45 minutes

• 55 minutes

• 50 minutes

• 60 minutes

When solving elapsed time problems, what tool is used to visualize the time intervals?

• Number line

• Graph

• Calendar

• Clock

In a digital clock problem, if the start time is 4:35 and the elapsed time is 23 minutes, what is the end time?

• 4:58

• 4:57

• 4:55

• 5:00

How do you determine the start time from an analog clock?

• By estimating the time

• By reading both the hour and minute hands

• By looking at the minute hand only

• By looking at the hour hand only

If an event starts at 10:10 and lasts for 23 minutes, what is the end time?

• 10:35

• 10:33

• 10:40

• 10:30

What is the first step in solving a word problem involving elapsed time?

• Identify the start and end times

• Develop a plan

• Calculate the elapsed time

• Guess the answer

In the word problem example, what was the elapsed time for getting home?

• 30 minutes

• 25 minutes

• 21 minutes

• 15 minutes

What strategy is recommended for solving word problems in the video?

• Guess and check

• Trial and error

• Sides check strategy

• Keyword grabbing

What should you check to ensure your elapsed time calculation is reasonable?

• The start time should be later than the end time

• The start time should be earlier than the end time

• The elapsed time should be negative

• The elapsed time should be zero
