Getty-Dubay Basic Italic Alphabet Cards
Mom's horrible handwriting inspired us to use an italic handwriting program with our kids. It's difficult not to produce at least legible writing in Italics. Another plus is that manuscript flows into cursive - letters don't completely change, they just join. Not only does this seem sensible to us, but the many compliments the children have received on their handwriting have further encouraged us in this approach. (Children begin moving into cursive writing in Level C.) The last level gets into calligraphy toward the end. From there, follow up with a good calligraphy book for Jr. High/High School and continue handwriting as an art form! Instruction Manual applies to all levels.
These materials are specifically graded and include both instruction and practice.
