1. In my opinion, home schooling parents should not waste their money on all-in-one curriculum packages. Some children need more structure and/or intensive work in a particular area than these type of curriculae provide. That's why none of them include Math! Well, spelling, reading, writing, etc. may also need to be an individual curriculum as well.
2. In my opinion, home schooling parents should not waste their time using a learning tool (curriculum, game, online drill, whatever) that the child hates just because money was spent to get it.
3. In my opinion, Home school parents need to provide plenty of hands-on activities, fun field trips, movement, freedom to stay with a topic of interest for the whole day or week and put aside the lesson plans and other subjects, and take advantage of not having to "do school" at home. It's harder to "meet them where they are and slowly take them to where they need to be" than to just systematically follow each lesson in the chosen curriculum.
