number line worksheets

To solve number line worksheets, we will first learn how to draw a number line and then we will learn how to plot the points on the number line. Once we have learned to plot the points on the number line, a child is able to learn the concept of addition, subtraction and comparison of the numbers on the number line.  To start with, we will first draw a straight line, with the marks on it at equal interval. Now we will observe that the number zero appears at the centre of the number line. The two ends of the number line are indicated by the arrows and the arrows indicate that the line extend endlessly in both the directions. On the right side of zero appears all the positive numbers and the negative numbers appears on the left side of the number line decreasing from zero. Another thing to be remembered is that the more we move towards right side of the number line , the numbers goes on increasing and the more we move towards left side of the number line, the  number goes on decreasing.  SO if we need to compare the two numbers with the help of the number line, we say that we will first mark the two numbers on the number line and then check which of the two numbers appear on the right. The number on the right side represents the larger number and the number on the left side represents the smaller number.  In the same way if we need to add some of the number to the given number, we move to the right and to subtract, we move to the left side.
 To get biology help based on the curriculum of ap board of secondary education, we need to  visit to its site online and update our self and In the next session we will discuss about Order of Operations Worksheet.
