When you do sortings, you put things in different groups based on how they are the same or different.
Sortings can help make things easier to find or understand.
Examples:
She does the sortings of her toys by color.
The sortings of the books make it easier to find the one you want.
We do the sortings of the fruits by size.
The sortings of the animals by where they live is funny.
The sortings of the rocks by color is very hard.
The sortings of the candies by taste is fun.
