Lay the paper on a flat surface in front of you. Orient it so that the boxes run left-to-right across the paper in the direction that you usually write.
Write your first letter in the first box. For a short or lowercase letter, only go halfway to the top of the box. Ensure your letter fills the width of the box completely.
Write the next letter. If it's a tall or uppercase letter, go all the way to the top of the box when you write the letter. Again, ensure your letter fills the width of the box completely.
Finish writing all the letters. Check your work by ensuring that you have followed the rules for writing upper and lowercase letters. This means short or lowercase letters only fill half the box, while tall or uppercase letters fill the entire box.
