You are not alone. I have a nearly 12 yo ds with dysgraphia. He was diagnosised mid fourth in PS, but I already had plans to bring him home for 5th. I can’t speak to dyslexia, or how it inter-relates. He is a very good reader and is constantly reading. Writing on the other hand is such a challenge. Copy work is by far the most effective tool we’ve used for his printing. You have to be present and make sure he is forming letters correctly and gently catch him about to make a mistake, because having to redo or erase adds to the difficulty and frustration. We found copy work books unhelpful as they seldom used the exact font he uses, line size can also cause problems for spacing issues, and copying directly from a book was also unhelpful. It took me a little longer, but if I copied the passage down on to regular lined paper, taking time to exaggerate spaces so that he wouldn’t try to run all his words together, it was more helpful. I would indicate which lines he was to write on directly below what I’d written with an arrow and we’d make sure the page was double spaced. (My line, blank space, his line, blank space, my line, etc.)
We use graph paper a lot also, especially for math. He has trouble with keeping colums lined up, too little space on a page, and forming numbers. I print graph paper with 1/2″ squares from a website that allows me to choose how many squares per inch: http://incompetech.com/graphpaper/plain/
I didn’t even attempt spelling last year (our first year homeschooling) with ds. I really wanted to focus on the mechanics of printing — letter formation, spacing, alignment, uniformity, etc.– by using a model (copy work) and really getting them down before moving on to more difficult aspects of writing. You may find if he is still really stuggling with basic letter formation, etc, that holding off on spelling for a term or two, or event the year, is a good idea. We will begin using Megawords for spelling this year and will ease into written narration throughout the year. Letter tiles — even Scrabble letters, can take some of the work out of spelling when handwriting is very difficult and can really help a tactile learner. Bouncing a ball while spelling words orally can help an audio or kinetic learner. Use as many sense as possible, and lots of repitiotion. We are also using notebooking. I will have him dictate to me what he wants to write in his Science or History, etc. and I will write it down. We will then polish a sentence or two (so it says exactly what he wants it to) which he will re-write into his notebook as copy work.
I’m always looking for new ideas to help him, so I will be really watching to see what other suggestions people have to offer.
