Comparing Numbers and Distance From Zero

In lesson seven, students learn to compare numbers and distances from zero using absolute value and negative numbers. The lesson involves a task comparing the elevation of a submarine at -100 feet with four people: Claire, Andrey, Han, and Lin. Students use inequality symbols to compare elevations and absolute value to measure distance from sea level. They also explore rational numbers by plotting them on a number line and discuss whether negative values are always negative, as stated by Noah.

What is the main focus of lesson seven?

• Comparing numbers and distance from zero

• Understanding multiplication

• Learning about fractions

• Studying geometry

At what elevation is the submarine?

• 100 feet above sea level

• 200 feet below sea level

• 100 feet below sea level

• 200 feet above sea level

Which inequality symbol would you use to show that Claire's elevation is higher than the submarine's?

• <

• >

• =

• ≤

What is the absolute value of Claire's elevation if she is at 150 feet?

• 150

• -100

• -150

• 100

Priya claims her elevation is less than the submarine's and closer to sea level. Is this possible?

• No, because she is farther from zero

• Yes, because she is above sea level

• No, because she is below sea level

• Yes, because she is closer to zero

What is a rational number?

• A number that can be expressed as a fraction

• A number that cannot be plotted on a number line

• A number that is always positive

• A number that is always negative

If 'a' is a rational number, what is the value of '-a'?

• Always negative

• Always positive

• Cannot be determined

• Always zero

What tool is used to plot rational numbers in this lesson?

• Graph paper

• Number line

• Calculator

• Protractor
