My kids are eclectically homeschooled. They participate in sports, music and group homeschool activities. They enjoy learning, and at home they like to do science and history and Life of Fred. I require that ds practice his piano & violin for about 4 hours per week. We also do journaling and crafts and writing as we feel like it.
My difficultly lies in getting it all in, while also having enough free play time, and outside time and hiking time and field trip time. They grab short free play time between each activity, but then complain when I ask them to come back to the next lesson. But if we don't do the lessons, they complain of being bored and ask to do more. If I give them longer blocks of free play, then "school" takes all day, and we don't have time for a trip to the pond or the library or wherever.
