Divide the kids into groups of two or three. Give each group a bag with 5 random objects, then give the groups 15 minutes to come up with a skit using all 5 objects. Have them perform the skits for each other.
Play freeze dance.
Get a big roll of butcher paper. Have the kids trace each other’s outlines onto the paper. Each kid finishes the portrait of themselves.
Tape a piece of paper to each kid’s back and give each of them a pen. They go around writing something positive about each other on the papers, and then they get to read what everyone wrote.
Bring in a bunch of recyclables, some tape, string, and glue. In small groups, the kids use the recyclables to create sculptures.
Have everyone sit in a circle. One kid starts a story, the next continues, and so on. Maybe have someone else write it down or record it as they go, then later they can illustrate the story and make a copy for each kid.
If all else fails, ask them what games they like to play or have them brainstorm activities.
