If your students are anything like ours, you know how they can struggle through the long stretch from holiday winter break to spring break. We are always looking for a day in February to break from the standard schedule, whether it's a weather delay, early dismissal, or a half-day on Valentine's Day. This year, we will show our students how much we love them with a fun stats activity, instead of giving them a Valentine.
This activity was created after we shared the Trick-or-Treat Halloween Stats Activity, and AP Stats international all-star teacher Corey Andreasen emailed an idea for a Valentine's Day activity. Here is a link to the data.
