Stepping Back?

So I've been delving into the SRA reading system with Arianna through this book.

I'm really encouraged by her willingness to learn. All the time, everywhere we are, she asks me "What does that say Mama?", "Can you read that to me Mama?". She loves to sit down and 'read' books to her sister and loves nothing more than to have her face buried in a book. She's so proud of herself for knowing all of her letters and what sounds they make.

So I got this book and we started in on it but I'm wondering if we shouldn't take a step back. This is yet another system that works letter writing into its program and expresses why it is so important to the 'learning to read' experience.

Problem is that Arianna doesn't have enough fine motor control to do any of the exercises necessary to learn to write her own letters - she can barely do a straight line for that matter and that's perfectly fine for her actual age let alone her adjusted age.

I'm discouraged but at the same time I could use the next few months to just work on her pre-writing skills and spend some more time working on her math skills. But she is so eager to read and I'm really at a loss of how to teach her.

If anyone knows of anything, please let me know. Arianna will love you for it!
