A number line is composed of numbers in sequential order from a number A to a number B. For example, 1 2 3 4 5 would be a number line, if the numbers were arranged on a line with small "ticks" in order to define them. 5 4 3 2 1 would also be a number line, in a negative manner. Anything on the left of a number line is considered negative, anything on the right of a number line and the number 0 is considered positive.
Divide the distance between 0 and 1 into the same number of equal parts as the denominator of the fraction, count to the mark which is the numerator and put the fraction there.
eg for ¾ divide 0 to 1 into 4 equal parts (there will be 3 marks between 0 and 1 dividing it into 4 parts: 0____+____+____+____1) and put the fraction at the 3rd mark (0____+____+____¾____1); the marks only need to be visualised (in your mind) and do not need to be actually written, but if written in light pencil they can be rubbed out (0______________¾____1)
A negative fraction works the same way, except between -1 and 0 and the counting of marks is from the right hand end (-1____-¾____+____+____0).
A mixed number is a whole number plus a fraction, so substitute the whole number for the 0 on the number line above, eg 2¾ → 0___________________1___________________2____+____+____¾____3
Similarly for negative mixed numbers, eg -1¾ → -2____-¾____+____+____-1___________________0
Alternatively, convert the fraction to a decimal number (divide the numerator by the denominator) and mark the fraction at that point, eg ¾ = 3 ÷ 4 = 0.75 → 0____0.25____0.5____¾____1
With mixed numbers, again add the whole number, eg 2¾ 2 + 3 ÷ 4 = 2 + 0.75 = 2.75 so place the fraction there.

Why is the number line of a number is never negative?
A number line can have both positive and negative numbers. You can put the number line in any position, but often it is represented so that numbers to the right of zero are positive, and numbers to the left of zero, negative.
What symbol is used to represent one or more numbers?
put a line on top of the number for example a line on top of second number its easy
How would you use a number line to put integers in order from greatest to least?
Smaller numbers always go to the left of larger number on the number line.
How do you model your equation on a number line to show your answer?
You model your equation on a number line to using a bar model.
Does the number line have a beginning?
No. However, it does have to have a beginning number. beside the beginning number, on the actual line, you would put an arrow on the end of it, because numbers are infinite in both directions.
How do you put a line over a number?
You draw it. Or you can use the Math Input Panel (in start menu) to draw a line with numbers underneath.
What does a line plot look like?
you put all the numbers on a horizontal line and then put Xs above the numbers depending on how many of the numbers there are.
Can you make a straight line into curved line?
yes you can so if you put two lines meeting at a 90' angle then put as many marks on the lines but make sure you put the same amount of marks on each of the line then number the mark on one line then the number number you started with goes at the end of the line you havent numbered the join the numbers up
How do you teach the difference between negative numbers?
Put all the numbers - zero, positive, negative - on a number line. Positive numbers to the left, negative numbers to the right. The difference between any two numbers is represented by the distance between them. Thus putting numbers on a number line is a great visualization tool.
When you make a lineplot how do you decide what numbers to put on the number line?
It depends on what numbers you are using in your problem. For example... x > 2You would do a line plot with two in the middle and about two more numbers on each side.
Numbers found to the right of zero on a number line?
Numbers to the right of zero on a number line are positive numbers; to the left are the negative numbers.
What are the rules in adding numbers?
Line up the numbers and add from left to right. If you you have remainders put on top of the next right number and add to sum
