My son (right brained, dyslexic, dysgraphia, and other LD's) is struggling understanding and learning his multiplication tables. His teacher is really giving him a hard time about it and he's taking a hard hit on his self esteem. (cant homeschool until May

We tried the music CD's (he says they make him nautious and dizzy-- dyslexia thing???)
We tried Times Tales. Not good for him. Confused him, AND it only covered a small portion of the tables. Honestly, it confused ME too.
He does NOT respond well to flash cards and rote memorization, we learned that just dealing with the alphabet and his vocabulary words.
Any products, tips, programs that work well for his learning style?
I'm desperate!!!
