ARTH ping to help out a fellow FReeper!
When we homeschooled, I did math and English every day. I figured literacy was the most important thing to focus on. If they could read and calculate, then they could handle whatever else they were interested in and would tackle it themselves.
We generally did some science and social studies every day as well, but was more felxible about if we missed a day or two.
Art, music, gym, etc were catch as catch can.
We also counted everything we did as school. A trip to the zoo or a museum would count as science or social studies. When we went grocery shopping, I taught them how to figure out the bast deal for package size. That was math.
I think giving them practical, real life experience in using what they were learning both reinforced the lessons and gave them a reason to use their learning so they knew it just wasn’t busy work.
