If there's one thing I would go back and change if I could when homeschooling my older two children (grown and graduated now), it would be that I would have them watch more great educational videos online, instead of focusing mostly on textbooks.
(And I would let them have more time to pursue something they were passionate about. I'd rather have a kid who was passionate about something, anything - studying bugs, piano, building, classical literature, writing stories, etc. - than have a kid who did all the boring bookwork but never developed a passion in any one area.)
Sometimes, for some people, watching things is more inspiring and memorable than reading about it. It brings things to life more, helping you feel more and remember more. My boys would have really enjoyed and benefitted from more educational videos. There are so many interesting, good ones out there; what a shame we missed out on them.
So this year as I start school with my younger two, we are going to add some good videos, maybe starting our morning with them while the kids are still too groggy for reading. And we are starting right from the beginning, with videos on creation. God's Word and creationism has been under such attack in recent decades, and I want my boys to understand that science affirms - not contradicts - the Bible and a biblical worldview of creation. I want to give them reasons now to believe it, before the world tears their faith down (which it attempts to do at every turn).
