Plan on having A LOT of games in the house:
-build & destroy (ships etc)
-blocks that you stack & knock over by throwing bean bags (have prizes)
-pin the smokestack on the semi or bulldozer etc
-treasure hunt inside the house: write clues on index cards. Send them
around the house to find things, using household items. Have it end w/a
secret chest filled w/sand subtitute, coins, little fun prizes. Make the chest huge. You can use an old, soft, padded toy chest or paint an old ice
chest to look like a treasure chest (black, brown, gold etc).
-bean bag toss
-knock over the milk jugs/cans w/bean bags
Have little prizes from the party store
Have a train set up to go around the party table.
Set up a race track w/Matchbox cars etc.
You can string up a string across a door way or entrance way, w/other strings hanging down holding donuts. You have the kids kneel w/their hands behind their back & try to eat the donuts hands free. Fun & funny.
Edit: one more game. You get nine 2-Liter soda pop bottles, arrange then in a square together, throw shower curtain rings at them tring to ring the tops of the soda bottles.
