My first concept this fall is area and composing and decomposing shapes to find area.

Unconsciously incompetent: I can count up the number of squares in the shape

Consciously incompetent: I know there is a better way than counting all the squares, but I don’t know what it is. Or what if there are no squares?

Consciously competent: I can find area by making a unit square of any size and use the array model idea to find the area.

Unconsciously competent: I multiply the width by the height to get the area. I can do this to all the various shapes and put it all together.
