Usual strategies to enhancing writing skills in my classes

Currently, I'm working with preschool students (to be exactly: 3-year -old students or Pre-K), they're learning how to write vowels, numbers and how to trace lines, shapes and others.

Independently of the idea that they're learning how to write, I motivate them through the usage of their creativity; first, I show them the Wonderful moment of holding a pencil and express something, a draw, a letter, a name, all in creative and remarkable materials and ways to create in my students the enthusiasm of writing numbers in a dictation or identifying images through writing a vowel.
