# Counting Principles – Order Irrelevance

Order Irrelevance is the sixth blog post in a series about the Counting Principles. These principles are helpful when developing children’s number sense. It’s not enough for them to learn to count by rote, they have to develop a strong foundation of numbers and counting.

You can see the other Counting Principle blog posts here.

### What is Order Irrelevance?

It is the understanding that the order you count objects in is not important, what matters is that the objects in a set are counted once and only once. The set can be counted from left to right, right to left or from any other point.

### Why is Order Irrelenvance important?

Children need to know that the number is not attached to a particular object in the set, it is just a temporary tag that we give it when counting.

### Activities

Use concrete objects to count, then ask the student to start counting from a different object to see if the count stays the same.

##### Order Irrelevance Matching Cards

Students start counting on the green dot, they match the cards with the same number of dots. They have to start counting at a different object on each card.

If you would like to use these cards, they are a free download in my Resource Library (if you do not have he password, sign up for my newsletter and it will be sent to you):
