Tuesday, Nov 5 Lesson 5.1 Integers and Graphing

Objective: To use integers to represent real world situations.

Integers and Graphing At the end of this lesson you should be able to answer the following question. How can you use integers to represent data?

Integers and Graphing Integers are all positive whole numbers and their opposites.

Integers and Graphing Integers are all positive whole numbers and their opposites. Negative numbers are used to represent data that is less than 0. A negative number is written with a “-” sign.

Integers and Graphing Integers are all positive whole numbers and their opposites. Negative numbers are used to represent data that is less than 0. A negative number is written with a “-” sign. Positive numbers are used to represent data greater than 0. If a number does not have a “-” sign, it is assumed to be positive.

Integers and Graphing We can use a number line to display all integers. Integers less than zero Integers greater than zero are negative integers are positive integers zero is neither negative or positive

Integers and Graphing When an integer has a negative sign, we move to the left. When an integer has a positive sign, we move to the right.

Integers and Graphing A 10 yard loss would be written as what integer?

Integers and Graphing A 10 yard loss would be written as what integer? Because it represents a loss, the integer would be -10.

Integers and Graphing A 10 yard loss would be written as what integer? What would zero represent?

Integers and Graphing A 10 yard loss would be written as what integer? What would zero represent? No gain or loss.

Integers and Graphing 4 inches of rain above normal would be written as what integer?

Integers and Graphing 4 inches of rain above normal would be written as what integer? Because it represents above, the integer would be +4, or just 4.

Integers and Graphing 4 inches of rain above normal would be written as what integer? What would zero represent?

Integers and Graphing 4 inches of rain above normal would be written as what integer? What would zero represent? Normal

Integers and Graphing A $48 deposit into a saving account would be written as what integer?

Integers and Graphing A $48 deposit into a saving account would be written as what integer? Because it represents an increase, the integer would be +48, or just 48.

Integers and Graphing A $48 deposit into a saving account would be written as what integer? What would zero represent?

Integers and Graphing A $48 deposit into a saving account would be written as what integer? What would zero represent? No change in the savings account.

Integers and Graphing What integer is represented by the dot below?

Integers and Graphing What integer is represented by the dot below? Start at zero. Is the dot to the left or right?

Integers and Graphing What integer is represented by the dot below? It is to the right. How many spaces?

Integers and Graphing What integer is represented by the dot below? The dot is 6 spaces to the right of zero, or +6.

Integers and Graphing What integer is represented by the dot below?

Integers and Graphing What integer is represented by the dot below? Start at zero. Is the dot to the left or right?

Integers and Graphing What integer is represented by the dot below? It is to the left. How many spaces?

Integers and Graphing What integer is represented by the dot below? The dot is 11 spaces to the left of zero, or -11.

Integers and Graphing The number line can be used to compare and order integers. On a number line, the number to the left is always less than the number to the right.

Integers and Graphing We can also graph sets of numbers. { -4, 2, -1}

Integers and Graphing The temperature outside is 3˚. If the temperature drops 14˚, what will the temperature be?

Integers and Graphing The temperature outside is 3˚. If the temperature drops 14˚, what will the temperature be? -11˚

Integers and Graphing A football team receives the ball on their own 5 yard line. a. The make a gain of 15 yards on the first play. What yard line is the ball on? 20

Integers and Graphing A football team receives the ball on their own 5 yard line. b. What represents zero in this situation?

Integers and Graphing A football team receives the ball on their own 5 yard line. b. What represents zero in this situation? The 5 yard line, the original placement of the ball.
