After I taped all the poster boards down , I gathered markers , rulers , crayons and stickers for the kids to use to " enhance " t their poster boards , creating their own a little backdrop for their Lego creations . One drew Outer Space , one drew an Ocean , and several drew Roads and Trails ... The amazing thing about this party is how well it worked . For the first hour the kids were so quiet and in to their building they hardly made a peep . We adults almost forgot that there was a birthday party going on at all ... I think the age of the kids helped - no fighter over toys etc . that might happen with kids Miles age .

Question: What may have been your reason for getting poster boards along with the Legos ?
Answer: They could build their lego creations on the poster boards .None of the above choices .I wanted to make sure the kids had something to do after they were done with the legos .I wanted the children to add a background .
