Before your child can learn to write letters and words, they need to be able to form some pre-writing lines and shapes.
At approximately age 2, they should be able to draw a vertical line, moving to a horizontal lines at 2 and a half. A circle is then the next shape that they should be able to form. Close to 4 years old they should be able to form a cross, moving on to forming a square. Once they have mastered this they should then be able to form horizontal lines, working towards a cross and then a triangle.
