But I'm a bigger fan of positive rewards. If it's homework, tie the reward to better homework performance rather than a specific grade.
+1 to all of this, but also with some sort of natural consequence involving the loss/reduction of a time-waster (say, screen or phone time) until her grades are back up. Kids need a little nudge sometimes. I did.
I am for sure not a proponent of "let her fail." That strikes me as not only hostile, but as lazy parenting and poor support for your child.
