And they kept busy. And no fighting either. Since they all had so much to do they got a long quite well. I think that is one of the secrets to harmonious living, a common goal and lots to do.
They used a blanket for a door and my husband thought 10 pounds of nails. ( He went out one night after they went to sleep and either pounded or cut off the ends with a dremel tool. It took him 2 hours. It also lasted over 2 months. They had quite a good time until a huge storm came, I also think it had a little help falling down.
They learned a lot from this playtime. They used both math and construction skills. I knew they were listening when helping their father because they had no help with this at all. From the plans? to finding a door they did it all on their own. They learned teamwork. My oldest son said the best part was building it and now wants to do it again. He learned leadership and that it doesn't mean the same as bossiness or he would have trouble getting anyone to work with him. All in all it was a good experience that I hope to repeat.
