This Cinco de Mayo craft doubles as game: balero, an ancient Mexican challenge where your kids try to hike the ball into the cup. And the cool thing is, it's made out of a recycled Keurig Cup and other items lying around your house.
Bowls made of confetti! Great recycling art project--save all those leftover paper scraps (put in small bowls at each table). Collect a bunch and have the kids cut them up; Then make bowls made from confetti.
