You have a grid of squares, some of which contain numbers. Can you find all of the groups?

The numbers indicate how many squares are in each group. Initially you may be given more than one number in a particular group. Groups with the correct number of squares in them are shaded.
Groups with the same number are not allowed to touch, otherwise they'd form a group with a larger number. This group would contain more squares than the number in each square so would no longer be shaded.
The competed grid is a collection of groups, each of which is the same size as the numbers in its squares.
