Inspired by Krista Walden's Operation Elf, here is a free elf project for upper elementary students. As Christmas break approaches and your kiddos are less willing to work, provide them with an opportunity to participate in their own Operation Elf. Perfect if you have a buddies program with younger grades - and even if you don't, you can adopt a kindergarten or preschool class for the holidays. Then, get busy with scissors and glue and make your own bingo boards. The little ones will love them, and their teachers will love you!
