Cardinal Numbers
Cardinal numbers are the normal counting numbers like 1, 2, 3, 4, etc.
They are used to count objects.
They help us know “how many” in a group!
Ordinal Numbers
We use ordinal numbers to tell the order or the position of the objects.
Like 1st, 2nd, 3rd, etc.
It’s like saying:
- Monkey is the 1st.
- Giraffe is 2nd.
- Lion is 3rd.
They help us know “which one” in a group!
