I teach first grade in a Christian school and sometimes the curriculum, well, is boring. I am building up a collection of Veggie Tales to support lesson objectives when curriculum falls short. I let my own kids (10 and 18) be the critics. It passed. I find the teens like Veggie Tales (especially the crazy songs) sometimes more than the younger ones. Teaches Biblical morals and truths in a fun way.
Think the age limit should be 10 years old, not 12. My junior high Sunday School students say that it is too young for them. I was looking for something in their age group to help supplement their lessons.
