At our house, Dad is the principal. Although I make all the day to day decisions when there is problem, concern, or big decision to be made I go to him to get his advice and wisdom. It helps him to stay involved without being overwhelmed with every aspect of homeschooling [which as we Mamas know, can be a LOT]
I love this list of 7 Ways to Involve Dad in your Homeschool from Teachers of Good Things. It has 7 really practical and easy ways to keep Dad involved because as we all know, homeschooling impacts the entire way you do family!
