Know Your Numbers: Positions in a Sequence

In this activity, we will be writing the positions of numbers in a list.

 

Look at this sequence of numbers.

 

   2    4    6    8    10    12    14

 

We can number them using 1, 2, 3, 4 etc.

 

2	4	6	8	10	12	14
1	2	3	4	5	6	7

 

But it is better to use the words:

 

First, second, third, fourth, fifth, sixth, seventh

 

or the symbols

 

1st, 2nd, 3rd, 4th, 5th, 6th, 7th

 

2	4	6	8	10	12	14
1st	2nd	3rd	4th	5th	6th	7th

 

 

2 is the 1st number in the sequence.

6 is the 3rd number in the sequence.

14 is the 7th number in the sequence.

 

Does that make sense?

 

 

Let's have a go at some questions now.
