Run copies on red paper and laminate. These have lasted 4 years. Now you are ready to do the activity. I place the hearts on the perimeter lines of our gym. I put a dome on top of each heart.
Domes are substitutes for cones.
They can be ordered from Sportime or U.S. Games. They are great as they are easy to carry. You can also use hoops or deck rings - you just need something to keep the hearts from going all over the place. Designate a locomotor movement or animal walk for the students to do when the music starts. When an auditory cue is given, I use a whistle even though I don't normally use one, the students go to a dome, look at the heart, and do the exercise on the picture.
