Bubble Pop - Kids love bubbles! Get two or three adults with strong lungs or buy a manual or battery operated bubble blower and let children go nuts popping the bubbles.
Balloon Bounce - Depending on the number of children, get one or two balloons. Throw them in the air and show the children how to keep them off the ground, pushing and hitting them back into the air.
Crawl & Race - Clear a space and let children race each other on hands and knees from one side to the other.
Interactive Songs - Sing songs such as "Ring-Around-A-Rosey" and "The Hokey Pokey" along with the actions, teaching the children how to do them.
Musical Leader - Turn on the music and walk around the room, doing one action (patting head, stomping) at a time. Get the children to follow and copy the action. Also try imitating different animals.
Obstacle Course - Create a fun obstacle course out of pillows and larger toys and let children scramble over it to the finish line.
Pinata Pull - Buy or make a pinata using ribbons for easy access. Let children pull the ribbons in turns to open the pinata.
Simple Simon Says - Ask children to touch one body part at a time - nose, ear, mouth, knee... or swap it around and ask them which body part you are touching.
Treasure Hunt - Hide small treasures around the yard or room - simple things such as colored balls or blocks are just as fun as real prizes at this age!
