Handwriting is SO 19th century. Why should anyone bother with it? Many reasons.
Handwriting, especially in a clear cursive hand is an act of communication with style and grace. It can create a positive first impression, or solidify an earlier one (or mitigate a not so positive earlier impression). At an unconscious level, the message is that the scribner possesses a high degree of self-discipline and sophistication. And the message is all the stronger for becoming increasingly rare in the age of texting. Yes, you could argue it is elitist, but it is an element of elitism that almost anyone can master and benefit from. Certainly something a child can benefit from, even if they can't appreciate all the subtleties of the advantage they gain.
School Zone Grades 3-4 Cursive Writing is a great start for a child working on this discipline. The first half is straight penmanship drills, single then joined letters, upper and lower case. The second half is drills, but all answers to basic questions in geography, science, literature, and other questions, to make it a little more interesting.
A great suppliment to a child's education.
