The day before Thanksgiving break is sometimes seen as a wash to teachers. Half the kids are gone and you don't want to reteach content for dozen out of twenty-five kids. Instead of putting in a DVD, consider writing a toast.
This double-sided worksheet has students brainstorm the main points to hit upon (who will be present? What good things have happened this year? What are they looking forward to?) and then gives them space to write some brief thanksgiving wishes.
Turn it into a two-day activity by having students stand up and share their toasts with the class. Having a class party? Fill up cups with sparkling cider and juice to raise at the end of each toast.
This sheet is great for a Public Speaking or English class. And as thanks to my followers, it's free!
