I learned to do gingerbread houses this way from the kindergarten teachers. I asked how two teachers could supervise so many houses at once with such small children. They said the trick was to pre-cut the houses and "hot sugar" (see directions below) them together in advance, assembly line fashion, with two adults, no kids in sight! The hot sugar has no dry time and is very stable, so it goes FAST. Then at the party, each student gets their own bag of royal icing, a pre-made house, and a bowl of candy. The original pattern is the first one listed here, it is the easiest to mass produce and a great size and shape. Here is a post with lots of pictures of how they turn out.mother daughter "gingerbread" house party.
Now, about the other patterns, we used Keebler brand graham crackers which are scored this direction, some brands are scored a different direction, but it shouldn't matter at all. I cut them very, very carefully with a steak knife (serrated). If a piece breaks and you are short on crackers, you can glue it back together with burnt sugar (or perhaps royal icing.) My castle door broke about six times, but it was fine in the end and can be covered with candy if it bothers you. You can click on the photos to see full size photos. Also remember when gluing/hot sugaring pieces together to put the right side of the graham crackers facing out, it looks better than having the back of the graham cracker showing.

Train, note how candy inbetween the curved engine graham pieces fills out the train engine shape.

Directions for houses:
To assemble houses, use hot sugar. Melt about 1 cup of white sugar in a frying pan on medium heat stirring constantly. Then adjust heat to medium low.
Hot sugaring is dangerous, like hot glue, its very, very, very easy to get burned!
The points on the sloped cracker can be cut using scissors if you start cutting at the point, they aren't perfect, but it is fast. A stake knife cuts the points really well too, but is slower.
Its nice to have two people when hot sugaring the houses together. Then you can come up with a good system for assembling.
(We dipped both ends of both side walls at the same time. Then, we set them on the front wall while the second person attached the back wall. Once the four side walls were connected, we dipped the top of the house in the sugar and then added the roof pieces.
Royal Icing ( you can have several people each bring a batch of icing instead of making it all yourself)
3 egg whites
1 pkg powdered sugar (4 cups)
1/2 tsp cream of tartar
Beat egg whites and cream of tartar until foamy in small bowl. Slowly beat in confectioners' sugar until frosting stands in firm peaks and is stiff enough to hold a sharp line when cut through with knife. Keep bowl covered with damp paper towel while working to keep frosting from drying out. Store leftover frosting in tightly covered container or ziploc in refrigerator up to three days.
freezer bags work best for icing, regular bags tend to tear.
Plan about 3-4 houses per batch of icing.
Foil covered cardboard squares we used 7x11 my daughter's school asked them to bring 12x12 squares, whatever you like. Cut cardboard with an exacto knife or ask each family to bring their own boards.
