After you count, you already know how many there are. You do not need to count again. The last number you say is the total.
Mia lines up 5 apples and counts them: 5. Then she puts them in a pile. She does not need to count again. It is still 5 apples.
You can count in any order. Left to right or right to left, the total stays the same.
The last number you count is the total, no matter the order or the arrangement.
Count the dots. How many are there?
