The accessories of the great outdoors—you know, the dirt, trees, branches, and insects—make camping a veritable playground for young kids’ first trips into the wilderness. But after the marshmallows have been roasted (or when the rain starts to fall), passing the idle time inside a tent can become a sanity-straining chore. That’s where the aptly named Camp Gaming Kit ($35) comes in. It includes six dice, a deck of cards, a waterproof score pad, and rules to the dice game Man-or-Moose. Better still, by purchasing the kit you also help United by Blue—makers of responsible, durable goods—remove one pound of trash from the world’s oceans and waterways.
