A very simple activity that works on broad jump and running long jump. All you need is some painter's tape to put some distance markers on the floor
To jump as far as you can.
Put some painter's tape on the floor at different distances about one foot apart. Start with the broad jump by having the participants jump as far as they can (two foot take off and two foot landing). Give them each a few opportunities to improve on their first jumps. Progress to a running long jump by having them start a few steps away from the start line. Let them run up to the line and jump as far as they can (one foot take off and two foot landing). Again, give them a few opportunities to improve on their first jumps.
Make sure the jumper gets out of the way immediately to avoid collisions with the next people in line.
