The kids are basically home on their own this summer. Nana is there to keep them out of my hair three days a week, but apart from that, they're on their own to figure out what they're going to do all day, be it outside or playing games indoors. But this undirected summer "activity" selection more often than not ends up with the kids on the couch staring at the screen, with or without a game controller in hand.
This summer, we wanted to give them something to focus on, maybe attract their attention and learn something. We wanted to provide them a direction for discovery, and not necessarily some mandatory activities to try to force them to enjoy. Obviously, there are chores to complete. And there are some activities that are mandatory for this discovery, but I think we've worked out a good plan.
