Abby from The Inspired Apple has the most adorable idea for a snowman theme! I bought it last year and loved it! You can find it in her TPT Store!
It's called "A Snowman Celebration!" It includes a party planning guide, a card template, centers, and so much more! The unit ends with a birthday party celebration for snowmen. Sounds silly, but if you know first graders, what a hit! The children bring in a gift (from home, not purchased) that they feel would be a good gift for a snowman. It ties in nicely with Common Core because the students have to explain why they have come to this conclusion. Here is the snowman we made for our birthday party!
Cute craft idea:
And so easy! Just need paint, Popsicle sticks, glue, and googley eyes!
