Understanding Time Conversion Strategies

The video tutorial focuses on teaching students how to find the start time when given the elapsed time and end time. It reviews key concepts such as start time, end time, and elapsed time, and demonstrates how to use timelines for visualization. The lesson includes examples of solving problems using digital and analog clocks, as well as word problems. The instructor emphasizes the use of the hills and mountains strategy to break down time intervals and solve problems effectively.

What is the main objective of today's lesson?

• To calculate the total elapsed time

• To find the start time when given the elapsed time and end time

• To learn how to read an analog clock

• To find the end time when given the start time and elapsed time

What does the term 'start time' refer to?

• The time an event ends

• The time an event starts

• The total duration of an event

• The time shown on a digital clock

What is the purpose of using a timeline in this lesson?

• To practice drawing skills

• To make the lesson more colorful

• To calculate elapsed time

• To visualize events in sequential order

In the mountains and hills strategy, what do the hills represent?

• Days

• Hours

• Minutes

• Seconds

When using the hills strategy, what is a 'friendly number'?

• A number that is even

• A number that is a multiple of 10

• A number that ends in 5

• A number that is odd

How do you convert an analog time to a digital time?

• By using a calculator

• By looking at the clock hands and counting by fives and ones

• By counting the number of hours and minutes

• By guessing the time

What is the first step in solving a word problem using the sides check strategy?

• Drawing a timeline

• Finding the end time

• Writing a statement

• Calculating elapsed time

What should you do if you are not comfortable making a large time jump on the timeline?

• Use a calculator

• Guess the time

• Make smaller intervals that you are comfortable with

• Skip the problem

What is the final step in solving for the start time using the timeline?

• Checking the answer with a calculator

• Drawing a new timeline

• Subtracting the elapsed time from the end time

• Adding the elapsed time to the end time
