Skip Counting: Overview, Questions, Preparation

Skip counting deals with counting non-1 amounts, such as skip counting by 2, skip counting by 3, skip counting by 5, 10, or 100. It is a method of counting numbers by adding a number to the preceding number each time. For example, skip counting the numbers by 2, we get 2, 4, 6, 8, 10, 12, and so on. There are three things you need to remember.

Skip count is possible by any number.

It helps to count the sum easily.
In multiplication tables, skip counting has a massive use.

Skip Counting Forward

Using this concept, you add the same number over and over to skip count.

You can start with any number. If you normally count (like 1, 2, 3, 4, 5, 6), add 1 to get the next number. If you want to count by 2s, add 2 to get the following number.

You can skip 1, 2, 3, 5, n numbers.

Skip Numbering Backward

You can subtract the number over and over to skip count and move backwards.

You can start with any number. If you normally count (like 1, 2, 3, 4, 5, 6), subtract 1 to get the next number. If you want to count by 2s, subtract 2 to get the next number.

You can skip 1, 2, 3, 5, n numbers.

As skip counting always returns a sequence of numbers, you might find it useful in the chapter sequence and series. The weightage of this chapter is 5-6 marks.

1. How to skip count by 10?

Solution. Skip count by 10 gives a multiplication table of 10 if we start counting from 10. Hence we get:
10
10+10 = 20
20+10 = 30
30+10 = 40
40+10 = 50
50+10 = 60
60+10 = 70
70+10 = 80
80+10 = 90
90+100 = 100

2.Skip counting by 2s, starting from 67. 

Solution. Add 2 to 67 

67 + 2 = 69 

Add 2 to previous number 69 

69 + 2 = 71 

Keep on adding 2 to the previous number we get 67, 69, 71, 73, 75, 77, 79....so on. 

3.Skip counting by 5s, starting from 119. 

Solution. We will start the series by 119. 

Add 5 to 119 

119 + 5 = 124 

Add 5 to previous number 124 

124+5=129 

Keep on adding 5 to the previous number we get 119, 124, 129, 134, 139, 144, 149, and so on.
