We enjoy reading "The Gingerbread Baby" by Jan Brett around this time of year and doing gingerbread activities.
This year we used graham crackers, frosting, mini candy canes, and sprinkles to make a gingerbread house. Our houses never work real well with this method unless I use a glue gun to put the pieces together before hand, but I was going for things we already had in our house. I didn't use a glue gun before hand and we opted for a flat top house once it kept falling apart on us. My son still had a blast with the sprinkles (as you can see).
All of my other Gingerbread Activities I have shared before. You can check out loads of links from posts I have done in the past.
As you can see I have been doing gingerbread stuff since before my current preschool was around. :)
