“This tells the story of the Good Samaritan and also gives the background for it — why Jesus told it. It includes applications for us now and, of course, connects to the Gospel. For children 4-10, though adults may also enjoy it.” – from SermonAudio
These can be just listened to for enjoyment (Psalms 1:2) , used for homeschooling, or in other formal instruction. Some kids like to listen to them while they fall asleep.
