Others have shared very good advice. Here is another you might consider.
Many on this list home school. Maybe you do too? As the father, subjects I
teach (which helps relieve my wife of at least some subjects) are Bible,
catechism, and church history.
I give the children work to do during the week, and we review and go over it
on Sunday afternoon and evening, after the services.
For Bible I use the Sabbath Bible Survey Tests and Assignments book at
. (eg, they prepare for the tests
during the week, which I administer grade, and go over with them on Sunday)
For Shorter Catechism and WCF I use GI Williamson's books. For Larger
Catechism I use the resource at http://www.puritans.net/curriculum/
For church history I use the textbooks and teacher manuals at
