Warming up (tag, with throw/ catch, run free run/play free)
divide the group into groups of 5 (it's also possible to have a different number, but adjust if necessary).
make a box, for example 8/8 or 10/10 or 12/12.
Of each group of 5, 1 person is a catcher, the others are the field players (if you have more than one group, you can put the catcher(s) of one group into the other group).
The catcher tags 1 or 1½ minute and you count how many tags have been made (one player can't loose and stays in the game).
The catchers that start tagging (recognizable because of the jacket / ribbon) and
distribute the other remaining children per group in the box with a ball. They pass over the ball and walk free.
The catchers try to tag someone who doesn't have the ball, so someone who has the ball is not allowed to be tagged.
The player approached by the catcher must get the ball as quickly as possible.
