Counting by a Fixed Number

When you count by a fixed number, you are adding the same number to the previous count each time. This allows you to skip count and quickly find the total of a given set of numbers.

Example:

If we start counting by 5, it would look like this:

1. Start at 0
2. Add 5: 0 + 5 = 5
3. Add 5: 5 + 5 = 10
4. Add 5: 10 + 5 = 15
5. Add 5: 15 + 5 = 20
6. And so on...

So, when counting by 5, we are adding 5 to the previous number each time.

Key Points:

• Counting by a fixed number means adding the same number each time.
• It helps in quickly determining the total of a set of numbers.
• It is a form of skip counting, which is a useful skill in arithmetic.

Remember, practicing counting by a fixed number can help improve your mental math skills and make arithmetic calculations easier and faster.
