Dear Mary, was just surfing for info and noticed your message. I have taught children's church for 7 years both in finland and Canda. Speaking of the parables, I have found an excellent teaching material. ( you may have heard of this already, since this message of yours have been here for almost a year now, thought I'd still leave you a note)
The material is called "the Parables of Christ" and it is published by CEF Press, located in Warrenton, MO. this material has 12 lessons which can be divivded into two- thus giving 24 lessions if you so choose. I have used one lesson per church. and have used this material for the entire year- twice already.
hope tihs helps you and may God bless your ministry with the children!!!
In Him, aura
