This sounds a lot like my DD, too. But she's really good at memorization and is begging for some "new big idea" math so I told her we would do a little push on math facts adding/subtracting 1-20 for a month (as folks have recommended here before). Rods have helped for sure. But she'll touch fingers and mutter and know and forget facts... And she definitely thrives on being shown approaches to problems instead of "discovering" (seriously the math at her school is going to be too much for me... But there are other kids in the same boat so I hope with a bit of math fact hot housing we can join up and ask for a real accelerated math group). Showing her column math and regrouping made things exciting enough for her to really want to work on facts. She's just aching for new ideas, challenge... She intuited negative numbers and certain patterns in graphs and fractions etc etc at an early age... But yeah those little facts!
