I know a lot of homeschoolers don't believe in grades. Honestly, I don't really either. My state doesn't require them and in the elementary years they don't really mean anything. I make the kids redo their work until they get it right anyway so they all get straight A's, right? Actually, I have a couple of reasons for doing grades, even though I don't really believe in them.
1. Motivation: Some of my kids are motivated by those big letter "A"s at the top of their work. And once in a while I will offer a reward for good grades, which in our house mostly mean they worked hard to learn the stuff we are studying.
2. High school transcripts: In high school we need to keep track of grades for their transcripts. Colleges will want to see them.
3. Practice: When they get to college, they will be graded on their work. They might as well get used to it now. It's also given me a chance to practice keeping records for their high school transcripts.
Ultimately, it's up to you (and possibly your state) whether you record grades for your homeschool or not. If you do and you want a form for record keeping, this is what I use. Hopefully it will help you:
You can download the editable Excel version here. It's in the same file as the planner pages so if you downloaded those, you already have these.
You can download the write-in pdf version here.
