t oday we will identify and represent positive numbers on a number line identify = point out...
TRANSCRIPT
TODAY WE WILL IDENTIFY AND
REPRESENT POSITIVE NUMBERS ON A NUMBER
LINEIdentify = point out
Represent = stand for
Positive number = number greater than zero
Number line= line in which indicate the sequence of numbers
NUMBER LINE!
Number lines are used for many things! A few of the uses of number lines are to:
Add Subtract
21 7 86543 130 9 10 11 12
5 + 3 = 8 6 - 5 = 1
POSITIVE NUMBERS
All numbers that are greater than zero! Remember that if a number does not have a
sign next to it, then it is positive!
Some examples are:7, 8, +8, 9, +19,
1,000,000 etc.
Non-examples are:-1, -3, -1,000,023
NUMBER LINE
a number line is a picture of a straight line on which every point corresponds to a
real number and every real number to a point.

HINT
If you don’t see a negative or positive sign in front of a number it is positive.

LET’S PRACTICE IDENTIFYING POSITIVE INTEGERS!
Steps:1.Look at the point 2.Look at the point above the number line3.Where is it located?4.Write that number down!
A.
Where is point A located?
That’s right! 6

LET’S PRACTICE IDENTIFYING POSITIVE INTEGERS!
Steps:1.Look at the point 2.Look at the point above the number line3.Where is it located?4.Write that number down!
x.
Where is point x located?
That’s right! 11

LET’S PRACTICE IDENTIFYING POSITIVE INTEGERS!
Steps:1.Look at the point 2.Look at the point above the number line3.Where is it located?4.Write that number down!
t.
Where is point t located?
That’s right! 0

NOW LET’S PRACTICE REPRESENTING POSITIVE INTEGERS ON A NUMBER
LINE!
Steps:1.Look at the number you are going to represent2.Look at the number line and think where it is going to be placed3.Represent on the number line above the number
Represent point x on the number line Draw and label it on the
number line at 8
X.

NOW LET’S PRACTICE REPRESENTING POSITIVE INTEGERS ON A NUMBER
LINE!
Steps:1.Look at the number you are going to represent2.Look at the number line and think where it is going to be placed3.Represent on the number line above the number
Represent point a on the number line Draw and label it on the
number line at 0
a.

NOW LET’S PRACTICE REPRESENTING POSITIVE INTEGERS ON A NUMBER
LINE!
Steps:1.Look at the number you are going to represent2.Look at the number line and think where it is going to be placed3.Represent on the number line above the number
Represent point b on the number line Draw and label it on the
number line at 13
