In a typical homemade battery (like a penny - nickel battery), the layers are usually a copper - based coin (penny), an electrolyte - soaked medium (the square, often paper soaked in vinegar or salt water), and then a nickel - based coin (nickel). So the correct sequence involves starting with a penny, then the electrolyte - carrying square, and then a nickel on top to form the cell.

Answer:

The first step is to put a penny down. Next, you place a square (presumably a soaked paper square, like in a penny - nickel battery setup) on the penny. To finish the first cell, you place a nickel on top of the square.
