I learned this warm up activity at a professional development where John Hichwa was the presenter. Kids were happy and active for the entire 3 minutes.
The basic premise is that the gym is divided into thirds, where each third represents each Olympic medal, bronze, silver, and gold. I use one free throw line, extending all the across the gym, as the bronze, then the halfcourt line represents the silver, and the opposite freethrow line represents the gold. The object, of course, is to stay at gold and win as many golds as possible.
All students begin at bronze level, music begins and kids find other kids to play against. Winner advances to next level up and loser falls back one level. Of course, you can go no further back than bronze.
It looks like students smiling and running to specified location in a controlled manner. Because you have to play against someone to move to the next level, kids will talk to and play against anyone who is available. Great activity, to do at the beginning of your program. It can be somewhat of a icebreaker.
Enjoy! I like to play with the students to increase and model enthusiasm. I like it as a warm up or instant activity. Today I did that, then did push up and sit up physical fitness tests, then did a small outdoor run. Good day.
