Have the students stand in a circle and hold hands. One child (rabbit) stands in the middle. Another child (fox) stands on the outside. As the song is sung the “trees,” or students in the circle, decide if they will open or close their branches at the end of the song. At the end of the song the fox chases the rabbit. They may go around the circle when chasing, or they may cut through the middle of the circle as long as they only duck under arms that are raised. Remind the students in the circle that once the song is over and they choose to put their arms either up or down, they may not change their arms until the reace is over. This will prevent a student from getting clothes-lined by accident. The fox takes over as the rabbit if he catches the rabbit. The rabbit takes over as the fox if he doesn’t get caught. I usually give a 10 second countdown for the chase and no more. The rabbit is considered safe if not caught by the end of this time. After the students know the song well enough to sing the song well independently of the teacher, then the song can be used for low la.
I have a small-ish music room, but all of my furniture is against walls, so we are able to play this chase game without too many problems. If you have no movement space, consider taking your class out into the beautiful spring weather to play the game. Or, I have seen a similar song/game in which the game involved the fox and rabbit having to weave in and out of the windows without skipping any of the windows, and the first one back to their original spot in the circle wins the round of the game. This might be a good alternative if you have little room. Have fun!
