Hi
I like to be off around Thanksgiving and Christmas too, so I came up with something for our lessons in first year. My ds is only turning 5 next month, so we’ll be doing K and starting the day after his birthday, hence this schedule hasn’t formally been implemented yet.
We will start in January, right after the New Year’s holidays and my birthday on the 4th, and continue all the way, with lots of time off towards the end of the year, starting in late October. Just plan six weeks anyway, just a nice divisible number like 42 weeks instead of 36-week year, which is 7 six-weeks. Then you have 10 weeks off in total, which you can factor in later as vacation time, sick days, etc. You could also do 49 and only have 3 weeks off, but I think 10 weeks give you plenty of time to plan, travel, etc. Good luck planning!
