Super easy craft:
Buy the large bucket of Crayola Wonder Clay (or it is called something close to that, it is air drying "clay") in white from Mikes- with a 40% off coupon it is $13.
Use plain white paper plates as a base, glue cotton balls onto it. Add glitter if you want. Make snowmen out of the clay. You can color the clay with plain old regular markers after it is dry. The color comes out nice and bright. We use a black marker (the thin ones are best) and make dots for eyes and the mouth. We make a carrot nose with an orange marker... they can go as fancy or simple as they like.
You can also work glitter into the clay before you make the snowman for sparkle. I use felt to make a scarf and real twigs for the arms. The kids LOVE this craft. We are doing for the third year in a row at the kids request!
This is a really good choice for older grades, as the kids are pretty much past wanting to make anything 'cute' and they have done all the glue and paper type crafts before.
