Sorting is when you look to see how objects are different and then put objects in groups.

Cookie Monster had 4 plates of cookies. All the plates had 2 cookies on them except one plate. That plate had 3 cookies.

3 plates of cookies that had 2 cookies on each plate. One plate of cookies had 3 cookies on it. That is sorting.

Sorting can also be when you match things that look alike into groups.

You can sort things by color, shape, size or objects. Here I have a bunch of animals. How can I sort these animals?

You can sort by animal groups. Let’s move the animals into groups.

After I sorted the animals I can see I have a group of 3 dogs, 2 cats and 1 mouse.
