Hi A. and Happy Thanksgiving!
I saw your request and had to reply...I feel for you. Math was always difficult for me growing up and has also been a burden to my daughter. Working with children having learning disibilities and having a son with "autism" I've learned to research and reach out to as many helpful resources as I can (library, internet, interaction groups, etc.).
Some individuals have difficulty learning and when they hinder a person's way of learning, it's a "disability" that needs to be addressed. Learning disabilities include problems that deal with mental processes--such as reading difficulties (dyslexia), writing difficulties (dysgraphia), difficulties in paying attention or concentrating (attention deficit hyperacticity disorder) and difficulties in performing mathematical operations (dyscalculia), which might be an area where your daughter needs support.
Also, working with her teacher, school counselor and other learning support staff to know more about what help is available (tutoring, assessment evaluations, counceling, etc.) should lesson the burden on you and your daughter.
I'm not an expert, but I have been working with children ages 5 on up to 21 with mild to severe learning disabilities as a profession for almost 9 years and feel I can offer the help and support to get you going in the right direction.
Reaching out to others, admitting there is a problem and being an advocate for our children is a great step in ensuring their success!
P.S. If you enjoy reading, I'd recommend "My Thirteenth Winter" by Samantha Abeel. It's a true story/memoir of a girls struggle to overcome her phobia with math and all that's associated with it... from telling time, remembering her locker combination, or counting out change at a checkout counter--and she was in seventh grade.
"But in her thirteenth winter, she found the courage to confront her problems--and was diagnosed with a math-related learning disability. Slowly, Samantha's life began to change again. She discovered that she was stronger than she'd ever thought possible--and that sometimes, when things look bleakest, hope is closer than you think."--Scholastic Inc.
