There are two games with Day 1. They are Simon Says and a variation on Follow the Leader. Simon Says has one person guiding the other in motions. Follow the Leader has a leader guiding the rest of the group.
how to play
This game follows the normal Simon Says rules. One person stands in front of the group and says "Simon says (action)". They can mix it up by just saying the action. If someone does the action without "Simon says" in front of it, they are out."
Follow the Leader
You need a colored rope. Everyone in the group holds onto the rope. The person at the front guides them around an area. When their turn is done, switch who the leader is.
