Another way

Could you teach her (as well as your other students) a different way of doing the math where she doesn't have to carry?
For example, if the problem is 39+15=___ instead of adding the ones and then the tens she could add the tens (30+10=40) then, add the ones (9+5=14) then, add both sums together (40+14=54).
You could also teach your students how to use what they know about numbers and the base ten system to do mental math. For example, in the same problem above they would know that 39 is one away from 40. If they take that one from the 15, it leaves them with 40+14=54.
Does that make sense?
