Bad weather often forces us inside (I’m the only teacher who has to change their lesson plan based on the forecast!).
We have to be creative inside. Middle and Older kids were supposed to learn how to do a rugby scrummage (or scrum). We at least got to practice it indoors. The front line players have to bind together with their arms, then engage with the opponent’s line. One team puts the ball into the scrum, which is “hooked” out by the feet.
In actual rubgy, the two teams push mightily against each other to get an advantage and either team can get the ball. As you might imagine, the scrum can be quite a rough place. We use an uncontested scrum, where there is no pushing, and only the team that puts the ball in can hook it out.
Another bad-weather activity is bean-bag horseshoes. This works on throwing skills. Bean bags tossed that land completely inside the hoop for a “ringer” are worth three points, touching the hoop is worth two, and the bean bag outside but closest to the hoop gets one point.
