A couple other constellations are Cassiopeia and Cepheus. The Queen and the King. I can find Cassiopeia since it looks like a "W" and is found on the other side of Polaris from the Big Dipper. Cepheus is then to the right of Cassiopeia.
Since these are fairly near Polaris, they are in the North and due to the light pollution at my house being worst in that direction, I can't always see these constellations.
