I'm grateful for things that are free so I'm all over this November Gratitude Calendar (see below) from Traci Smith, author of Faithful Families. The prompts make it easy for a family with children to have a simple conversation about the things for which they are grateful.
I also love resources that can be used at home by the whole community of faith and this calendar ticks off that box too. Consider printing copies to make available to the whole church this Sunday in addition sharing it via social media.
