The kids were separated into groups of three or four. Each group received a bowl of candy, a bowl of icing, plastic knives and plates for everyone. With patience and perseverance, they built their house with 6 graham crackers, then decorated with a variety of candy. The best part was that since my students are a bit older (Grade 4 and 5), there were no tears if a house crumbled.
Some ate their houses before leaving while others brought theirs home. I was very impressed with how well this turned out and highly recommend it as an activity even in middle school!
