I bought some foam snowflakes at Michael's and I had the kids use glue, sequins, and fake snow to decorate them. I let them go wild with their creativity. I had three students at a time come back to a table and decorate their snowflakes.
Here are the items I used:
Step 1: Squeeze glue onto the snowflake and then smear around with a q-tip.
Step 2: Decorate with sequins and/or fake snow.
Step 3: Let them dry!
