Do better at math: teach it less
Interesting: a long article about an experiment from 1929 in which kids were taught no math at all (they spoke English instead, e.g. telling stories etcetera) up until grade 6. Before the start of grade 6, these kids were crappier at the "standard" math tests (but better at general "story problems"). By the end of grade 6, the kids with no elementary-school math were as good at the "normal" math tests and (still) better at more general story-type problems.
The moral would seem to be to not teach kids "formal" math until much, much later than we currently do.
