- Bake things: some great winter recipes can be found here and here
- Make your own popsicles: pour juice or Kool-Aid into popsicle forms or ice cube trays
- Make miniature igloos out of sugar cubes or marshmallows: have a contest for roundest, most creative, and tallest
- Bring back summer: have an indoor beach party. All you need is those summer toys out of storage, crank the heat, and let the kids run around in their bathing suits.
- Have an indoor campout: build tents out of pillows and blankets, make s’mores and tell ghost stories
- Grow an indoor garden: with a grow light and some soil, you can plant everything from flowers to herbs, and the kids will have something they can care for until Spring
- Have a family card or game night
If not snowed in:
- Go to the library: get books and see who can read the most pages or get movies and have a marathon
- Pottery decorating: there are places to decorate your own pottery in most cities. On a smaller budget, pick up supplies at a craft store and decorate your own pottery.
