We had great success doing study before school but I now start 30 mins earlier and we just don't have time anymore. The morning is a much better time to tackle new concepts and challenges when the kids are fresh if you can manage it.
I afterschool in math, spelling, reading and general knowledge/science.
We tackle a range of topics in the car on the he way to school. During our school and gym runs we listen to classic audio books as well as historical fiction and true history stories. We have at least 4 hours a week of audio learning and that still gives us time to listen to some dance music on our less perky days
as well as stories we listen to educational songs in science and grammar and occasionally math facts. We were listening to French and Japanese audio but gave it up.
When we get home we eat first, the kids have to eat Or apparently they will die
then I gauge their mood and decide if outside running around first or after will work better. It varies a lot day to day.
They all sit together at the table and do math, spelling and their school homework ( of which they get way too much) it takes between 45 mins and 1.5 hours to do it all. Some days are less other days are the he entire afternoon.
Then they get to play, free choice til just before dinner when I send them to shower.
After dinner they go to bed basically strait away to read. We use this reading to explore topics of geography, science and vocabulary and reading extension. Careful selection of books makes after schooling so much more efficient! I am careful to make sure we cover both fiction and non fiction as well as all the old stories we all heard as kids. We review topics periodically to ensure they remember them. Some nights I read to them other times they read individually. Every night my son reads to me.
On some days of her he week I have only one child in the car with me at a time ( to and from sports events) I take advantage of this time and they read advanced books to me. This way they get extra practice and I can correct those little errors in pronunciation.
I try to sneak in some writing here and there. It seems to be the hardest for us to after school as they really don't want to write anything after a full day at school.
Oh and we after school art as well but I don't do anything but provide resources and ideas. Art is what they CHOOSE to do in their free play time.
