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

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

19. 3 plates of cookies that had 2 cookies on each plate. One plate of cookies had 3 cookies on it. That is sorting.

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