How to I get a child to see the difference between these two problems, when the key words, "more than" are in both problems? One problem is addition and one subtraction. It seems so simple, but she can't tell the difference. She just keeps seeing "more than" and wants to add the second problem. I need a bridge sentence.

Have you tried using manipulatives to help her undertand in concrete terms what each problem is asking?
Would this help?
Option 3: Alternatively you could spend some time on discussing the concrete concept of more and less.
Count out two piles of pennies.
Pile A: with five pennies - pile b: with three pennies.
If she uses the manipulatives to actuall see the relationships between the two groups of pennies in relation to the concept of more or less -- perhaps it will help her move along to abstract concepts and finally to word problems.
It might take many problems over a period of time for her to grasp the concrete concept of more and less.
