Sit down right now with a pencil and paper and write the 10 Commandments.
Could you do it? Or if you did, were they in order?
The 10 Commandments have a purpose for being in the order they are in, but that is a whole different Sunday School lesson we won't get into right now.
Below is Commandment One for you to print out. You can use this several different ways. First, you can let the kids color the page, cut it out and take it home. You can let the kids color one sheet together and hang it on the wall. Or, you can already have the sheet colored before class and play a Sunday School game with it.
Whatever you choose, remember don't assume your Sunday School class knows anything. It's better to teach something they already know again than to not teach them at all.
