Have you ever wondered that while you were teaching a classroom full of children? "How Do I Get These Kids To Listen?" by Ed Dunlop is a great help! Whether you have have been teaching for fifty years or this is your first time, this is a must read! In the first two chapters he talks about the efective use of visuals. Flannelgraph is a great visual aid, but you need to change it up a bit! There are a lot of great ideas in the book on what to use. You can put your memory verse on posterboard or on an overhead projector. Both will get the kids attentions, depends on how big your class is.
He also talks about being prepared for your class. You should start studying next week's lesson, today! Pray over your lesson, memorize it, be gathering your visual aids together. Be early to class. Never wait until the last minute, your students deserve better and so do you!
