I believe it was the 2nd edition. I'm not sure if you need this but on this thread I posted an updated volume 1 and 2 as my email changed and some links broke with that switch. https://forums.welltrainedmind.com/topic/722252-bfsu-lesson-plans/ I'm glad you find it useful! 😊

I know this is old, but in case anyone searches here anymore... I typed up these BFSU Vol 1 lesson plans and worksheets for my family. Feel free to use or share if you find them useful. (Trying to make myself feel better about the amount of time I spent working on these.... And because I love his program and agree that it needed an organizational overhaul!)
