Snowball Throwing Contest
Snowballs are fun, free and safe for children. Rather than throwing snowballs at each other, have your kids practice their accuracy on a snowball throwing range. Stomp down and flatten a circular patch of snow so that it is level. Then you take several spray bottles filled with water and different food colorings and spray these in rings radiating out from the center, like a dart board. Assign point values to each ring and have the kids throw the snowballs in order to score.
Snowball Over the Mountain
This is a fun game that emulates snowball throwing indoors, for those who don't have snow or like to stay warm. First fill up several white balloons with air, the more kids playing, the more balloons you're going to need. Stretch a white sheet and fasten it to chairs or floor lamps to construct a wall between two groups of children. This is the mountain. Let the kids enjoy trying to slap the balloons over the top of the sheet to hit each other.
Flag in a Snow Stack
This game is the wintertime equivalent to finding the proverbial "needle in a haystack." All you need is a watch, stick and white cloth. Tie the stick to the cloth and have the children take turns hiding it. You can have one child hiding it while the others stay indoors to deepen the mystery. Let the kids loose, and time how long it takes for the flag to be found. The kid who hid the hardest to find flag wins.
