Someone gets to be the Fox. All others are Chickens. The Chickens have a barn. The Fox can't get in the barn, so the chicken are safe there.
The Chickens ask the Fox what time it is. The Fox says a number. Then the Chickens come out of the barn as many steps as the number the Fox says. When the Fox says "midnight", the chicken run back to the barn, because that is when the Fox can catch them.
When the fox catches a Chicken, the Chicken changes to a Fox and help the Fox catches more Chickens.
The game ends when all the Chickens are turned to foxes.

2. Freeze Tag

Any number of children can play. The looser of "One  Potatoe.." (a counting game) is 'it'. That child tries to catch the children. If you get tagged you have to sit down. If one player gets to a frozen player, they can unfreeze that person. The last one frozen is 'it' for the next game.

3. Hide and Go Seek

Any number of children can play. One child hides their eyes and counts up to 10. all other children hide. When they finish, the person says: "Ready or not, here I come".
The person who counted tries to find the others.
If you are back to the pole (where the person counted) without getting caught, you are not 'it'.
The last one found is 'it' and must count for the next game.

4. Tag

Our favorite game is Tag. It can be played  by how many children want to.
To decide who is 'it' you have to say 'not it' and the last kid who says, is 'it'. If you are 'it', you have to tag anyone you  want and the person who was tagged has to chase other children.
That's all.

5. Space Boys

The game is played by many children. Some are good and some bad. They all have powers that can help them glide, turn into birds or into different colors, fly over a volcano, fly in space or others. There're also monsters and they can turn others into dogs or other animals. 
There is a castle and the kids have to get there. In the castle there are a mother and a father who have mind control and have a rocket ship in space.
The monsters have a spaceship too. With the help of their mother and father, the kids have to fight the monsters and beat them. They have to reach a button in the monsters' spaceship to turn the others into humans again.
