Okay, so imagine you have a really big room with lots of boxes in it. You want to know how many boxes are in the room, but you don't want to count them one by one because that would take a really long time.
So, instead, you decide to divide the room into smaller sections, like squares. You count how many boxes are in each square, and then you add up all the numbers to get the total number of boxes in the room.
Now, let's say you want to do this for lots of different rooms. Some rooms are bigger than others and have more boxes, so you need to use different sized squares to count them.
For example, if a room is really big, you might use big squares to count the boxes. But if a room is really small, you might need to use smaller squares to count the boxes.
The pattern that you follow when deciding what size squares to use is called the scaling pattern of occupancy. It's like a rule that tells you how to divide up the room so that you can count all the boxes without missing any.
Does that make sense, kiddo?
