A sweet idea to keep the kiddos busy during the holidays! 
We love messy tubs (often called 'sensory') at MCP. We use rice throughout the school year and at the holidays add a bit of peppermint extract. Plastic candies can be found at your local dollar stores, craft store or on-line shopping site.

Not interested in rice all over the kitchen floor? Use white shredded crinkle gift bag paper for an easier clean up.
After the holidays you can add polar animals!
