Hey guys!
So, I'm helping out with a class of 4-6yr olds for my church tomorrow night.. turns out the lady in charge can't make it. So I'm stuck, I have to think of something by tomorrow night! So, if you have any ideas, they'd be greatly appreciated. There's usually 12-15 of them. It can be anything like a bible story&a craft. Just a craft. Coloring. Easy games. Snack.. anything..
Thanks so much guys!

I think you are on the right track. They are pretty young so I would do a little bit of structured stuff, and end with just letting them play. Perhaps start with a Bible story about some simple concept like "caring", then you can let the kids take turns answering some very simple questions like "what is your name? Who is one person you care about?" Then you can pass out paper and crayons and have them draw a picture of someone they care about. You can talk to them individually as they draw about what they are drawing. And you can close by telling them how much Jesus loved children and cares about children.

Then you can have a simple snack like juice boxes and cookies (keep it really easy to hand out and not messy). Have them throw their garbage away, and then let them work on their pictures some more or play until their parents come to get them. Make sure they bring their pictures home.
