My dd likes the comic books from BA, but has lots of other living math books she prefers. Stuart Murphy, Number Devil, Greg Tang books and the Time Life I Love Math books were favs in first grade. Now she likes Murderous Maths, MOEMS problem solving books and some by DK that cover number history, economics, etc.

For curriculum, we sort of unschooled math with living books until she was 7, then moved quickly through the Singapore Math Standards elementary books.

I wouldn't buy BA, yet. Check your library or find used copies of the some other living math books.
