Count and Find Missing Numbers

Now, in the following worksheet try to find the missing numbers on the number line.


Skip and Count on Number Line Worksheet

In the previous worksheet, we have seen non-interval counting on the number line. Now we’re heading on to a different version of the above activity. Instead of finding digits one by one, you have to skip count by 2, 3, or 5 to find the next value. For example, you have been told to skip count by 2. So, if the first number is 0, then the next number will be 0 + 2 = 2. See the following image for a better understanding.

In one row, you can write 10 numbers. Some of the numbers are missing from the chart. Just go through the chart carefully and find them all.


Finding Integers on Number Line Worksheet

Integers are numbers that can either be positive, negative, or zero. But an integer will always be a whole number, you cannot call a fraction an integer. In this task, you will do some number line exercises with integers.

You have to find both positive and negative numbers to fill the number lines in the following worksheets. See the following image for a better understanding.

Finding Integers on Number Line

But remember some things before proceeding.

  • When you are adding or subtracting a negative number, the seemingly bigger number is always the smaller. For example between -20 and -30, -20 is greater than -30.
  • If you subtract a bigger number from a smaller one, the result will always be negative.
  • When you multiply or divide two negative numbers, the result will always be positive.

So, let’s start to find those missing numbers one by one in the following worksheet.


Finding Missing Fractions on Number Line Worksheet

In this activity, we will find several missing fractions on a number line. In the following worksheets, you will find several number lines with some fractions written on them. But all the series of these fractions are not complete. You can see some fractions are missing from each series. You have to find all these fractions. See the following image for a better understanding.

Finding Missing Fractions on Number Line

Here are some tricks and tips to find fractions.

  • To find a numerator, you have to count the dot of the top space from the beginning till you reach your problem spot. The number of dots you just passed is your desired numerator.
  • To find the denominator, just count the number of spaces between the beginning and the ending number of a number line. The number of spaces you got is your denominator.
  • In the end, write the missing fraction with the numerator and the denominator you got from the above two steps.

Now, after understanding the above discussion, solve all the problems given in the following worksheet.
