This is a cute project I've done with Kindergarten and Grade 1 students.
You simply give them a variety of sizes of doilies (you can do just two like my sample above or do the more traditional three). Glue them onto blue paper (students can draw snow and snowflakes on it first with white chalk or a white pencil crayon)
Then, let them embellish the snowman with scrap paper,
scrap fabric, buttons, sequins, glitter, felt, etc.
You can collect small twigs outside and then I hot glue these on for the arms.
They turn out soooo cute!
