My son brought a version of this idea home from preschool and it couldn't be simpler. All we needed was a piece of paper and something to write with. Each person took a turn. First they had their hands traced onto the paper.
Then I wrote "We're thankful for (Name)" at the top of their paper. The other people in our family worked together to list ten things we love about that person. I wrote everything down on the paper.
I was surprised how much our family gained from this simple activity. Not only did it remind us to be grateful for the wonderful people who make up our family, but it was also good for the kids to see how very many things we appreciate about them.
