This is a wonderful resource for anyone who works with children of any age! I would highly recommend it. I have bought several copies and distributed them to our children's church workers and preschool dept. I think it would also be beneficial for middle school workers, too.
This book is a must have for every children's ministry department. Each teacher who is working with the kids at your church needs to have their own copy (and it should be required reading for the position!). It is an incredible collection of extremely applicable techniques that anyone can do (with a bit of practice) to totally transform the way the Bible is presented to little people. I have read it cover to cover, and am on my second time through. Also worth getting is the accompanying DVD, "The Master Classroom", where you can watch Aaron Reynolds leading a teacher training workshop with hands on techniques. Fabulous!
