I use many, but the most popular among the kids is "The Day it Snowed M & M's"
I usually do it on the first snowfall of the season and have a stash of M & M's to sprinkle on their desks while they write.
They then draw a picture to go with their story. The pictures are bright and colorful.
If I think of more that I use, I will post them.
It has been 70 here, so I'm not yet into the winter season!
