Many long years ago, when I first started my homeschooling journey, our homeschool looked very much like "school at home". I used a textbook-style boxed curriculum, I graded every page of written work and kept meticulous records. I assigned grades and issued a report card every 9 weeks. I put a lot of pressure on my kids (and myself) to make sure they were doing things on the typical public school timeline, and keeping grades helped to show they were jumping through all those hoops.
We schooled this way for a few years. As I became more comfortable with home education and more knowledgeable about learning styles, educational methods, and how to foster real learning - our homeschool evolved. The way we "do school" now couldn't be further from the way things were done at the beginning of our journey! One thing I stopped doing was tracking and assigning grades.
