Choose a school that doesn't give your kids much homework and you will survive
my kids get SOOOO much homework it is very difficult for us to pursue after school sporting activities at the higher levels. Fitting in language is usually done in the car to and from school and sports. Piano practice often gets missed as it is the least time sensitive activity they do. sigh.
To get it done we dedicate part of each weekend to homework and at least 2 hours each Saturday to extra study activities ( usually Saxon math as we all see that as most important) if they didn't have 6 hours of gymnastics training each week and taekwondo training too we wouldn't be struggling. Kids have more time free than we do!
I think the trick is to prioritise what is most important to learn. We prioritise gymnastics, math, taewkondo, reading, language, piano and history in that order ( at the moment anyway) Get a routine going, try are to stick to it. And finally use ALL the dead time. There is far too much time wasted in the car, before mum gets out of bed, after dinner and in front of the TV. my kids don't watch TV. Occasional movies that's it. In fact my daughter needs to watch an hour of TV for a school homework assignment and the teacher actually came to check with me if it was possible she could do it!
Homeschooling would be easier for us but it isn't a road we want to travel for a few more years. My kids LOVE school.
