My Favorite Promotion Sunday Tradition in Kids Ministry

Do you have any traditions or special ideas for back-to-school season or Promotion Sunday? Something you do every year that encourages kids to reflect on the past year but also get pumped for the year ahead? A special way to celebrate the start of a school year or moving to new ministry classes/small groups?

This video or slideshow shares pictures and clips of special events, Sunday mornings, mid-week programs, etc. Set it to an upbeat worship song your kids loved from the year, and you're all set!
I like to show this video recap on Promotion Sunday every year and use it as a launching point for small group discussion questions like:
