Steenrod squares are the simplest interesting example of stable cohomology operations. We will give roughly four constructions of Steenrod squares. This lecture is entirely about classical homotopy theory. It will assume a basic understanding of cohomology, and knowing that cohomology is represented by Eilenberg-MacLane spaces would help.
