School districts have a homeschool liaison generally listed on the district website depending on which district you live in. They tend to be helpful and supportive.
School districts offer a reimbursement for non-religious homeschool supplies up to about $86 per student from kindergarten up. You just need to fill out a form through the district requesting the reimbursement (typically due Oct 1st), and then submit receipts by May.
Overall, homeschooling reporting in MN is very easy. There are no portfolios to turn in or required number of school days, etc. There are also so many wonderful resources right now to encourage parents- books, podcasts, online conferences, etc
Schools use 7 hours a day because of wasted time. Children spend time waiting and distracted. Home school families generally spend 3-4 hours per day. Beside study time, learning happens in the car, at the store, everywhere and anytime they are receptive.
Students work on their assignments independently part of the time - not so distracted by other students! Then they have free time to enjoy family and other children!
