Scared by Big Numbers

We continue to work on 2 step problems here with DD1.  She is still struggling.  We had very easy problems today. Even tho I had her act it out. I could see the sullen I'm so confused look on her face.  This is a different expression from the sullen I don't want to do it look.  Working with the problem  I rephrased it made it a line drawing tried again in a more Visual Math Method.  Once I did that consciousness began to dawn in her head.
Then she was able to actually understand what she is doing. (15 minutes per problem is a bit of a problem).  So we went on to the next problem.  yet again I got the blank sullen stare...

here it is in a nut shell you sell 500 hundred balloons 235 were yellow and 176 were blue, the rest were red.  How many were Red?
DD1: "The Rest."
Ha ha ha ha shes right
Mom: Ok how many were Red?
DD1:  I Don't Know!
this could go on for hours... I went into more detail but I could see. The learning train had left the station and she was not on it...

I tried it with pictures of balloons but she didn't want to wait for me to draw 500 balloons and have her cross out the various amounts... Then I had a memory flash in my mind of how scared I used to be of huge numbers Anything over 10 was HUGE so 235 and 176 were scaring her.
So I reworded it
you sold 5 balloons at the fair 2 were blue and 2 were yellow  how many were Red?
DD1: One Mom... yes!
Mom: Now you sold 500 balloons at the fair 200 were blue and 200 were yellow. How many were Red?
DD1: 100 Mom... ok what did you do
DD1: well 2+2 is 4 and 5-4=1 same thing for hundreds
Mom: so do that same thing on the BIG SCARY numbers...
DD1: oh add the yellow and blue?
Mom: YES!
DD1: And then take the answer away from 500 to get Red balloons??
Mom: YES!
And that is how she did her word problems today 35 min later she had only done 2,  two step word problems  but hey she DID THEM!
