Games for One

Color walk
Have your child gather sheets of construction paper or a stack of mismatched hand towels and lay them down in a path all through the house. (To keep her from slipping, tape down the construction paper or towels with painter's or masking tape, which won't ruin your floors.) Tell her to keep colors separate, so there won't be, say, three sheets of red paper in a row. Once she's done, the challenge is on: Can she walk from one room to the next by stepping only on certain colors? Can she make it from one end of the house to the other, stepping only on blue and red? Can she manage it on all fours, or by hopping?

Balloon volleyball
Yes, volleyball usually takes more than one person. No, you don't have to play this version. Why? The whole fun of this game is for your kid to play both sides. Blow up a balloon, set up the sofa or a chair as the center line, and have your child run back and forth to hit the balloon before it lands on the ground. See if he can keep it aloft for 21 turns, the usual winning score in volleyball.
