When learning how to homeschool two different grades, establishing mutually understood house rules for school hours is an important step. Guided by what works for your family, you should all agree on the following: daily start and end times; scheduled break times for meals, snacks, and play; the lessons to be completed each day; and expectations for behavior while school is in session. If other family members are home during the school day, make sure they’re on board with the rules, too.
