So this one is really simple. Create all the possible shapes you can make using only 5 squares. You're on a 2D plane, and squares must connect properly, ie not diagonally or in the middle of two other squares.

Using circles cuz they're easier,

and ignoring rotations and reflections cuz they're redundant and tedious.

Both 4's and 4 of the 3's can be reflected into new shapes.

That would make 18 in all.
