There’s no specification in the law. You are free to decide how much of each subject to cover.
In elementary years we always did reading, writing and math activity/lesson each day. Then–another subject area: Science, Social Studies, Foreign Language, Art, Music, PE. We had exceptions to that “schedule”–where we skipped everything for a field trip or really involved project we were doing.

Then, for High School, the student was given a certain amount of work to accomplish in a week–because we had some once-a-week classes that they needed to prepare for that. Sometimes, they would tackle all of one subject in a day…or sometimes divide it up a little bit of each subject per day. It was up to them to figure out the best schedule.

It’s really up to you to figure out what works for you.
