Growing up we had a Thanksgiving tradition fostered by my mother. During the course of the day each person would take a slip of paper and write down what they were thankful for. The slips got folded and placed in a basket but the writer remained anonymous. Anyone attending dinner participated. At the end of the day we would each pick a slip, read it out loud to the group and then try and guess who wrote it. It was a wonderful way to gather and reflect.
Many of us ask our students to name things they are thankful for at this time of the year. I have always felt it was important to bring students back to the basics in this sometimes superficial world we live in...to remember the traditions and reasons for holidays. This year, consider helping students create Vine videos (6 seconds each!) about what they are thankful for. I've linked the site here. Then, share them with families via email or any other means you have available to you.
I hope you so have so many things to be thankful for this year that you could never name them all.
