When do children typically start learning cursive letters?

Cursive letters are a style of handwriting where the letters are written in a flowing joined up manner. There is no standard age at which children will learn this style. Many private schools believe that teaching a cursive style is developmentally beneficial and will start teaching children around the age of 5 years old. However many schools in the US public system no longer teach cursive letters instead relying on proficiency in keyboard skills.
