Explaining Algebra

My daughter was recently diagnosed with a learning disability with regard to math. Her current Algebra teacher only explains a concept one way and it must be done "her way", if not, it is marked incorrect. I am frustrated as she will not explain concepts in a different manner so that my daughter can grasp the information. Am I expecting too much as a mother to have a concept explained in an alternate way; one that she understands?

New to the forum here and hoped someone else may have experience this and could guide me.
