I think all of DeeDee's ideas are right on -- and that you shouldn't worry about drilling/speed at this point. Here's an additional, slightly different approach: There's a couple of places online that assess where kids are at regarding different categories of math, and then work on them from there. So, no need to repeat stuff she already knows, and no need to skip out on the stuff she doesn't know. I haven't tried any of these, so can't make any recommendations, but I know a lot of kids like learning this way, and it can be pretty low key if the amouunt of work done (games played) is kid driven:
Math Whizz -
http://www.whizz.us/parents/index.html-- $19.99/month
Smart Tutor -
http://www.smarttutor.com/home/homeschool.asp -- it's English AND math, but has less math categories than math whizz. -- $17.99/month with free 2 week trial
DOMA (math assessment) and Unique Math -
http://www.letsgolearn.com/lglsite/Unique_Math/educators/ -- Same content as Smart Tutor (but only math), but different assessment, and you pay a flat price for the whole year. I think the Homeschool Buyer's Coop has a special on this right now.
Plato Learning has individualized math, too, but a) it's hard to get and b) it's not a full curriculum at this age.
ALEKS has a program, too, that starts at 3rd grade math level.
Hope that helps.
