Tuesday, Sept 27 Lesson 5.1 Integers and Graphing

Objective: To use integers to represent real world situations.

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

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

Integers and Graphing Integers are all positive whole numbers and their opposites and zero. Negative numbers are used to represent data 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

Integers and Graphing Integer and sets of integers can be graphed on a number line.

Integers and Graphing You will need the number lines I handed out yesterday. When drawing on these number lines, draw lightly. This will be used for several weeks.

Integers and Graphing Graph -7 on the number line. To graph an integer on the number line, start at zero.

Integers and Graphing Graph -7 on the number line. To graph an integer on the number line, start at zero.

Integers and Graphing Graph -7 on the number line. Move to the left for a negative integer and right for a positive integer.

Integers and Graphing Graph -7 on the number line. Move to the left for a negative integer and right for a positive integer.

Integers and Graphing Graph 6 on the number line.

Integers and Graphing Graph 6 on the number line. The dot is 6 spaces to the right of zero, or +6.

Integers and Graphing Graph -11 on the number line.

Integers and Graphing Graph -11 on the number line. The dot is 11 spaces to the left of zero, or -11.

Integers and Graphing On a number line, the number to the left is always less than the number to the right. And the number to the right will always be…..
