Thanks for starting this thread, I think this could house some great information.
SonCatcher - Yes that is the program. I will get back here after a few discussions today to explain more about some why's as I don't know much about it. Some of why she liked it might have been cost, I think it's free and they give you a computer and printer. My niece did run into one problem, she wanted to write a paper on abortion and it wasn't allowed. No 'touchy' subjects.
For what Cath4life says is not good about Seton, is exactly why I love it. However, it is important to understand, it is not, nor does your life only have to be 1 thing, and the book work takes so little time...
The bookwork is typically no more than 3 hours per day, when doing it. By 11:30, sometimes by 10:30, I'll get a call from the oldest saying she got all her subjects done.
I like to have them call me and let me know what they finish. They get the sense of accompishment and shared joy (of course then I re-focus them, I am 'Dad').
If I'm home for work, I'll sit with the first grader and pump through 10 pages of math with her. Then she gets to be math free for a week, and loves it.
I love Seton because I know that with all the field trips, art classes, homeschool group outings, they are still getting some core reading, writing, math, phonics and are being graded on it. They test high, and will be able to enter college no problem.
What this does then, is allow for the other things to happen in the afternoon / evenings - they are all in sports, they go to the community center for art, clay class, they do plays through the city. Every Friday they go to a Catholic church and use the rooms to do community classes / religion stuff with other Catholic moms and kids.
Having that structure where they get the quarterly grades and can see the advancement is key for me.
