I've got a few posts about teaching history brewing in my head. It's a massive, messy, muddled subject, and I have massive, messy, muddled thoughts on it.
While I wrestle with what I want to say and how I want to say it, enjoy Wanda's favorite history video, "history of the entire world, i guess" by bill wurtz. Since it has just shy of 150 million views, you've probably already seen it, a few times, so treat yourself and watch it again. (Whether you consider it kid-appropriate is up to you, it's fine in our house, but you may want to pre-watch it before sharing it with your kids.)
