Counting Backward by 10

To count backward by 10, we need to start with a number and then subtract 10 from it, then subtract 10 from the result, and so on. The correct option that shows counting backward by 10 is:

Option B: 10, 9, 8, 7, 6, 5, 4, 3, 2, 1

Explanation:
Starting with 10, we subtract 10 to get 9, and then subtract 10 from 9 to get 8, and so on until we reach 1. Therefore, option B is the correct answer.

Let's have a look at the other options:

Option A: 10, 9, 8, 7, 6, 5, 4, 2, 3, 1
This option is not correct because it shows the numbers in a mixed order. It starts with 10 and counts backward by 1 until it reaches 4, then it jumps to 2 and counts upward by 1 until it reaches 3, and finally, it ends with 1. This is not counting backward by 10.

Option C: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
This option is not correct because it shows counting forward from 1 to 10, not backward by 10.

Option D: 10, 8, 9, 7, 6, 5, 4, 2, 3, 1
This option is not correct because it shows the numbers in a mixed order. It starts with 10 and counts backward by 2 until it reaches 8, then it jumps to 9 and counts downward by 1 until it reaches 4, then it jumps to 2 and counts upward by 1 until it reaches 3, and finally, it ends with 1. This is not counting backward by 10.

Therefore, the correct option is B, which shows counting backward by 10 in the correct order.
