My class is directed to follow these steps in order to find the answer:
1. What is the problem telling us? (Have your child read the telling sentences.)
2. What is the problem asking us? (Read only the question.)
3. What are our clue words? (Maybe make a poster that has an addition side and a subtraction side. List the different clue words and allow your child to refer to the poster as necessary.)
4. What process should we follow? (Again, use the poster to determine what you're going to do.)
I don't know if this will help at all, but maybe breaking it down into steps will make it a little simpler.
Also, just to make it more fun, I tell my students that they are detectives that have to find the clue before they can solve the problem. I write the clue words onto magnifying glass shapes on my poster.
