Comparing and Ordering Integers: Lesson 3.2 Insights

In this video, Mr. Math Log teaches how to compare and order integers using number lines. The lesson covers both horizontal and vertical number lines, with practical examples involving temperatures from various cities. Students learn to identify which numbers are greater or lesser by their position on the number line, and how to order temperatures from least to greatest and vice versa. The video also explains the concept of negative numbers and their behavior on number lines.

What is the main topic of this lesson?

• Solving integer equations

• Adding and subtracting integers

• Comparing and ordering integers

• Multiplying and dividing integers

On a number line, which direction do the values become greater?

• To the left

• To the right

• Upwards

• Downwards

Which number is less: -7 or -4?

• -7

• Cannot be determined

• -4

• They are equal

If 4 is to the right of 8 on a number line, what can we say about 4?

• 4 is not comparable to 8

• 4 is greater than 8

• 4 is equal to 8

• 4 is less than 8

Why is it important to graph numbers on a number line before comparing them?

• To make the graph look nice

• To visually see their positions

• To confuse the students

• To avoid using a calculator

Without using a number line, how can we determine that -2 is less than 0?

• By guessing

• By asking a friend

• By knowing all negative numbers are less than zero

• By using a calculator

What happens to the values as we move up on a vertical number line?

• They become greater

• They disappear

• They stay the same

• They become less

Which city had the coldest temperature in the given data?

• Truckee

• Davis

• Miami

• Tan Oaks

In the vertical number line, which city had the warmest temperature?

• Truckee

• Davis

• Tan Oaks

• Miami

What rule can we use to compare numbers on a vertical number line?

• Values become greater as we move down

• Values become greater as we move up

• Values become less as we move up

• Values stay the same
