Has anyone used Beast Academy as their *only* math curriculum? in General Education Discussion Board Posted May 25 So far, we have used BA as a supplement. But I don't know whether we'll continue this way or switch to just using AOPS when my son finishes BA. Does anyone have thoughts about this? He's done Singapore math for 5th grade and is now working through BA's year 5 stuff. He really likes their approach and I'm loosely planning to use the AOPS pre algebra with him next.
