Cursive worksheets are the best way to help students, especially young students, learn how to form cursive letters in a legible, consistent manner. This is because cursive worksheets use three lines instead of the two found on college-ruled paper. This third line helps teach both lowercase and capital letters.
Technically, no one has to use cursive worksheets to learn this style of writing. For example, in earlier times, students learned to write on chalkboard slates. The benefit of the worksheets, however, is in their structure and use of repetition to teach consistent cursive writing. Free cursive worksheets can often be found online and printed at home to further encourage practice.
