A few years ago my campus adopted a resource called Fundations. It is great for to use with your guided reading target group. They also have a handwriting resource that I use with the whole class.
The hand writing paper looks like this
When you teach the letters you have sky line letters (h), plane line letters (a), and worm line letters (j).
So Say I am teaching the lowercase letter h. I would say to students...Start on the sky line. Write a straight line down to the grass line then back up to the plane line curve and down to the grass line. ( While I am saying it I am also modeling it)
If you are interested in how to teach the other letters or in the paper leave me a comment with your email and I will email it to you. Still haven't figured out embedding documents. Sorry :-(
