There are alot of Home school programs that give all the lessons/books, tests, etc. for each grade.
I used Abeka for a short time while in a transition. The other poster is right, it takes time and dedication. But, the kids can miss their friends and activities associated with school. But, if you live in a fairly populated area (which I did not at the time, actually close to Amish), then there should be alot of local activities just for Home School children.
It's so sad to see something like this take place. What could posess a person to take their frustrations out on innocent kids?
Here in South Texas we have what are called umbrella schools, ususally established in local churches where parents can get assistance, the kids can take their state mandated testing and parents can find private tutors for subjects they may feel that they are not qualified to teach.
Prayers for the children, their families and the community.
