Activities with Grandchildren: The Summer Lego Challenge

This past summer I organized a Lego challenge with my grandchildren here, and my sisters' children who live in another state.  It worked like this:  One family would create a Lego structure, then post it on Facebook.  The other family had to create their own version of that structure, then create a new one and post them both.  We went back and forth until we had ten creations.  The children got to know their distant cousins a little better, and had a lot of fun with the challenges.  They made a lighthouse, a two-headed go-bot, a surfer's beach, and many other things.  The first challenge was "The Wall".
