If you did BA with your 6 year old, how did it go? Was it a gentle intro to AOPS-style learning? Did anyone have a rough go of it at first or was it a welcome addition/smooth transition?
My DS5 and I are currently working through Singapore 2 with just the TB/IP/CWP. I have Zaccaro, Borac, and LOF/living math books for additional enrichment, but I think we may end up hitting Beast this year regardless, and I'd would love to hear your experiences. Thanks!
