For history we use Ambleside Online. I won’t pretend that we’ve read every book, every year. But by and large, we’ve muddled our way through most of them.
For Years 9-11, another option would be an online AP history class like those at PA Homeschoolers.
We chose an online class for Year 12. Our oldest had taken Ancient Greek for 3 years, and was interested in a Greek History Class: Lukeion Classical History
A year of reading US Presidents’ biographies.
American History through movies.
Documentaries (Netflix, Amazon): BBC or Ken Burns
Hetalia. An anime series that can be found on youtube and other sites, this series is sometimes extremely inappropriate…. However, if you have a teen who struggles to be interested in history, and you have a rather relaxed parenting style, this series is brilliant. Set in post-WWII, the characters are the personification of countries around the world. Hetalia gave my daughter some really nice “hooks” on which to hang her history readings!
