I had the pleasure of being the substitute teacher for 8 (EIGHT!) two-year-olds yesterday. Being the day before Halloween, we read books about pumpkins and made pumpkins to take home.
Super easy folks, especially for the age group I had. I drew the faces, let the kids have fun coloring then stuffed the bags with newspaper (3 sheets was a good number for fullness). Twist the top, add a green pipe cleaner and leaves if you want. You're done.
This would also be a cute way to send lunch to school.
