Cut two squares of the copper foil sheet that are each 5.5 cm wide by 5.5 cm long. You can use a pencil to mark your measurement on the back and then use scissors to cut them out.
Cut two lengths of wire that are at least 12 inches long each. Splice and tin both ends of the wires with solder.
Solder one wire to pin A1 on the Circuit Playground Express. Solder the second wire to GND on the Circuit Playground Express.
Repeat this process for the remaining stomping pads, soldering three copper squares to GND and three copper squares to pins A2, A3 and A4.
Alternatively, you could have this be a solder-free project by using alligator clips and copper foil tape.
