Not sure how old the children are in your group. Two of our favorite games for the 1st and 2nd grade pioneer voyager group are musical chairs (you remove a chair not a child so that in the end all the children are sitting on one chair and a copy cat game where one person has to guess who is leading the group in coping their actions.
They also like building the tallest tower wthout it falling and seeing who has the tallest tower.
The sillier the better.
