The reason I'm asking is because I was afraid to just have my DS do BA 3 (all books) as it doesn't seem to cover everything that Math Mammoth 3 does. So, I've been having my DS(8) work out of both MM and BA every day. He told me today (this was our 5th day of doing BA) that BA is harder than MM, but he likes it a lot more and only wants to do BA.
I wish I could feel 100% confident in doing this, but something inside me churns at the thought. Maybe because it's new so there aren't many success posts of using it alone--actually I haven't seen one, so it's not that there aren't many, there are none.
My other worry is that he'll get caught up in 5th grade without having any math due to their release schedule.
I wish I could do just BA, but my fears are holding me back.
Is there anybody out there that is only using BA for their 3rd grader's math this year? If so, how is it going? Do you have any worries or fears about doing so?
If you are using BA as your main math program, but are supplementing with something else, what are you supplementing with, and how much of this supplementation are you doing?
I really don't want my DS to have to do two entire math programs this year. I was only going to have him do BA at a slow pace, finishing 3A and 3B only, but DS enjoys it so much more than MM. It's nice to see him smile while doing math.
