my son is failing math in elementary school how can I get turtoring assistance for him.

I agree that you should check into an evaluation. Many people do not recognize the impact of language on mathematics. You may request a comprehensive evaluation from your school. There are also many private psychologists in the field who offer reduced rates or pro bono work for individuals who need it. There are also organizations which subsidize evaluations or give assistance to those who have financial constraints. It all depends on the area in which you live. Check on line resources such as the IDA, interdys.org or the LDA website for warnings, symptoms etc. After you have an idea of "why" your child is failing, check into appropriate tutoring from someone who is knowledgeable about his type of learning needs. More of the same instructional techniques is not necessarily the best approach. Some learning centers offer group work in multisensory math, summer programs with math as a component and subsidized slots, etc. Some O-G training centers require a certain number of pro bono hours for therapists to receive certification, so do not be afraid to ask for a therapist who is being supervised but is in training. For a tutor, look for someone who uses manipulatives to introduce concepts and does not simply teach procedure and hand your child a calculator. Calculators are necessary tools and we must teach students to use them but students need to understand underlying concepts and operations as well as have some facility with facts to develop full math competency.
