Temperature Change and Final Values

The video tutorial explains how to determine the temperature at the end of the day given an initial temperature of -9° and an increase of 12° throughout the day. It uses a number line to visualize the temperature change and demonstrates a simple arithmetic calculation to find the final temperature of 3°.

What was the initial temperature at the start of the day?

• -9 degrees

• 12 degrees

• 3 degrees

• 0 degrees

How much did the temperature increase during the day?

• 3 degrees

• 9 degrees

• 12 degrees

• 15 degrees

Using a number line, what is the final temperature after the increase?

• 3 degrees

• 0 degrees

• -3 degrees

• 9 degrees

What is the final temperature if you add 12 to -9?

• 3 degrees

• 0 degrees

• 12 degrees

• -12 degrees

Which method can be used to find the final temperature more easily?

• Using a number line

• Using a thermometer

• Subtracting the temperature change from the initial temperature

• Adding the temperature change to the initial temperature
