Wow what an interesting read!! I have only just been looking at year round homeschooling this past weekend.
We live in Australia and my 3 girls are heavily involved in dancing. I have in the past organised our school to cooincide with the dance timetable, which lines up with our ps system here - 4 terms of 10weeks, with a 2 week break inbetween each, except for 7 or so weeks in Dec/Jan. The girls also perform solo routines in eisteddfods and so at times, like this past week, we have an eisteddfod and only end up being at home to do school one day out of 6. So not much school has been done. But we have about another 7 eisteddfods between now and October, which means many more days or weeks of not getting much school done. Most of October/November each year is spent getting ready for their end of year concert too - me sewing costumes, so we have always kept forth term a light school term (hope that makes sense). Anyway, usually when we have holidays from dancing classes, we take holidays from school too. But we have more time during holidays to do school as we have less time pressures and can enjoy our days together. This year we started school earlier in January than the ps do here.
My children are ages 8, 6, and 4. They are young so that means still very dependent on mummy for their schooling, for teaching them. So after this past week, I feel like we are getting behind a little. I am toying with the idea of doing school year round. I like the idea of 6 weeks on, 1 week off. But actually maybe school each day that we don't have an eisteddfod!!! I'd love to hear from anyone who has any other ideas for me :) Thanks!!
