It’s called Kids of Courage and is appropriate for children.
“Kids of Courage materials convey the struggles endured by persecuted Christians without including graphic descriptions or photos, or age-inappropriate concepts. Nevertheless, parents and teachers are encouraged to preview the materials before sharing them with their own children, as they know their children best.”
Note: You will need to register at the site for the free downloads.
Adding a Kids of Courage Student Activity Book is a a great way to supplement a history or geography course when you study that country.
Hope this helps!
