This weekend we held our annual December S.T.E.M. event, building gingerbread houses with graham crackers and marshmallows. First we read the story of The Gingerbread Boy by author Richard Egielski. When we got to work with the materials, most builders chose to make their structures with a milk carton base, using royal icing "glue" to hold the graham cracker sides and roofs in place. Candy, cereal, and pretzels were used for decorating. What do you think of our constructions?
