Mastering Elapsed Time Concepts

How many minutes did Julia spend on her homework?

• 40 minutes

• 30 minutes

• 45 minutes

• 37 minutes

What is the first step in calculating elapsed time using a number line?

• Jump to the nearest ten

• Convert hours to minutes

• Draw a number line

• Subtract start time from end time

What is the purpose of jumping in tens on a number line when calculating elapsed time?

• There is no specific reason

• To make it more complicated

• It's faster and easier

• To avoid using a clock

When subtracting times for elapsed time, what do you convert the end time hour to if it's the next hour?

• The same as the start time

• 30 minutes past

• 100 minutes

• 60 minutes past

What do you do if the elapsed time crosses into the next hour?

• Restart the calculation

• Only count the hours

• Ignore the minutes

• Consider the next hour as 60 minutes past

What was the total elapsed time for Amy's homework in minutes?

• 36 minutes

• 40 minutes

• 30 minutes

• 45 minutes

Which method did not change when calculating elapsed time for Amy's problem?

• Subtraction method

• Number line method

• Clock representation

• All methods changed

How can you represent elapsed time visually?

• By a line graph

• Through a pie chart

• With a clock

• Using a bar graph

What is the learning target of the tutorial?

• To draw number lines

• To subtract large numbers

• To calculate elapsed time

• To draw perfect circles

How does the clock representation help in calculating elapsed time?

• By showing exact minutes

• By visualizing the time span

• It doesn't help

• By converting minutes to hours
