Right now, to go along with our morning Bible reading time, we're using this, with our 5 and 7 year old - but you could easily use it with yournger children as well.
It's "Honor Your Father and Mother" by Doorposts. It is so great for little ones - just a simple question, like "Do I obey my parents and do what is right, even when no one is looking"? On the same page, it will have an outline picture (perfect for coloring in) of a little girl or boy, or both, demonstrating the question. (like sneaking a cookie, or being a good example, or something like that) If you have access to a copier, you could print off one page for each child to color while you read the question, and the verses that go with it (verses are also on the page, written out). While the kids color the page, I read the question, and verses, and we talk about what the child is doing, and say something like - "Make a face like the little girl" - "Now show me the face and response she should have had"...etc...
It deals mostly with obedience and respect, but also has pages on being a good example, or being curdious...even forgiving parents in their short comings. I mostly just pick the one that applys most for us each day instead of starting at the begining...it's perfect for that. If you don't have a copier, you could just purchase one for each child...they aren't very much. Anyways, the kids love it - and it's perfect for holding their attention, and engaging them....plus, I feel like having them color it gives them something for their busy little hands to do, while at the same time reinforcing the lesson....HTH!
