I know I can't speak for everyone, but here in Nebraska, this weather really gets me excited to move and be outside. I know all of you in the Northeast are jealous!
#firedrillweather as my friend +Laura Kroll describes it!
With these unseasonable temps in January, students seem just as anxious as us to be outside. Although this is not always possible during the day, you can use the awesome Extension Move it (that my friend +Shelly Mowinkel shared with me) to get your students up and moving periodically during the day. It doesn't get you outside, but does allow for some fun movement in the classroom. This tool allows you to schedule those necessary "brain breaks" and easily incorporate movement activities that are so important regardless of the weather. So... Let's "Move it, Move it".
