Here are a few forms that may help you in maintaining records for your minimum 180 days school year. 🙂
You can keep this in your record keeping book that you will set-up to maintain attendance for your homeschooling year.
With this option you can choose to use it to keep record keeping notes on it. i.e. what you did in your schooling with each child etc.
Another record keeping option is to make sure dates are written on consumable pages. If your child completes schoolwork in a workbook of sorts. Make sure the dates are written on the pages. This also will provide record of your schooling days.
There are many ways to be in compliance with Option 3, Section 59.65.47
