Honestly, this is why we never found a great reason to have "the number."
The child that you have in front of you day to day is more than a number will ever tell you. You can parent for potential, with that number in mind...
You can't parent that way and do it lovingly and responsively, though-- it feels like being raised by vulcans or something. Might want to catch Rick Moranis' character in Parenthood if you haven't seen it in a while. Just saying.
Offer things-- and don't emotionally invest in whether or not they "stick" or for how long. DD didn't care for most non-fiction at that age. Some other kids don't like fiction. Or only want to read... Magic Treehouse books. Or Rainbow Fairies. (Barf)
I say this with all gentleness and with a fair amount of been-there-done-that:
maybe she just doesn't need pushing right now. Maybe she needs time to just be five and let the intellectual development fall where it may. Might be time to follow HER lead and not impose any enrichment ON her.
I'd also replace "do" with "try" in your questions to her about her interests and activities. That way she knows that she has your permission to say "no, thank you" even to something that she THOUGHT that she'd like-- but doesn't.
