4th Grade Math Problem

A friend's 4Th grade child was given this problem a few days ago as homework. I found it really hard - not sure how it could be solved without a computer (but maybe someone knows the answer).

Where the letters are numbers from 0 to 9 excluding 3. Find the values for each letter that would make this true:
show + tight = coach

I have an answer and my working in the comments and welcome other solutions people might have.
So, if you want a tease, don't click on the comments until you have a go. I don't want to taint your thinking with my brute force attack.
