Put the goals upside down and drape the net over top of them. Put the fake spiders on the web. Students scooterboard on their bottomside through the web. Put whiffleballs in a ghost bag. Students take turns throwing ghosts at the box from a designated line.
Students take turns walking across the balance beam using forward, backward, and sideways.
This is great fun for the students. If you think the older kids will think it is boring, you could have them come with a Kindergarten or first grade class and have them take the little ones through the stations. You can pick and choose which stations you would like to do, or create your own. I also turn the lights down to give a Halloweeny feel. Also, arrows on the floor or walls to indicate where to go to next helps the students.
