Camp out at home
Set up the tent in the backyard. Grill out and eat outdoors and play some outdoor family games. Then have an astronomy lesson. Study up on the constellations that are visible during the time of year when you are camping then lay out under the stars and see how many of them the family can identify.
Indoor Family Fun Night
There are times of the year when it is not practical to have an outdoor family night. Due to the rain or winter weather it may be impossible to plan an outdoor activity. Surprise the kids with an INDOOR active game night. Here are a few ideas:
There is a new family card game called "Loot" and it is a pirate game using merchant ships, pirates, pirate captains, and an admiral. This is a frugal family fun game. It sells for under $10.00 new. You may also be able to find a used copy at Amazon.com.
Plan an indoor scavenger hunt. Plant clues throughout the house and a special prize for the winner.
Make an indoor obstacle course. Use chairs, couch's, pillows, and walls to make a course that requires jumping, twisting, sliding, and turning.
Have an old fashioned pillow fight. Dad and Mom get in the middle of it. Your kids will love it!
Play an active game such as Cranium HullaBaloo. This is a game designed for the preschooler, but is appropriate for all ages to participate.
Plan a Karaoke family fun night. Jazz up the evening by turning it into an American Idol type of friendly competition. Use a Karaoke machine with microphone or a gaming system game such as the Playstation II American Idol or Karaoke Revolution Volume 2 - complete package.
Surprise the family with an indoor picnic basket complete with fried chicken, sandwiches, and dessert. Lay out a blanket in a room you would not normally eat in, such as a bedroom or the family room, and eat on the floor.
