Mrs. Lopez teaches Grade 7 students about calculating distances between numbers on a number line, emphasizing the use of absolute values. The lesson covers examples of finding distances between negative and positive numbers, explains that the order of numbers does not affect the distance, and introduces a formula for calculating distances between large numbers. Practical examples, such as changes in elevation and temperature, are used to illustrate the concepts. The lesson concludes with a summary and homework instructions.

What is the distance between -4 and 5 on a number line?

• 8 units

• 10 units

• 7 units

• 9 units

If you switch the order of two numbers on a number line, how does it affect the distance between them?

• The distance is halved

• The distance doubles

• The distance remains the same

• The distance becomes zero

How many units apart are -5 and -3 on a number line?

• 4 units

• 3 units

What is the distance between -1.5 and -2 on a number line?

• 0.5 units

• 2 units

• 1 unit

• 1.5 units

How do you calculate the distance between two large numbers like 580 and -200?

• Subtract the smaller from the larger
