Developmentally it is easier to learn Capital letters first and then teach Lower case.
Developmental teaching order is planned to help children learn handwriting skills in the easiest, most efficient way. As a result, children can transition quickly from learning the mechanics of handwriting to focusing on content and meaning—in all subjects. We teach printing first. After printing is mastered, we add the cursive connections.
Capitals to Lowercase
Developmentally, capitals are easier so we teach them first. The capital teaching order helps teach correct formation and orientation while eliminating reversals.
Learning capitals first makes learning lowercase letters easy. We teach lowercase c o s v w first because they are exactly the same as their capital partners, only smaller. By teaching capitals first, we have prepared children for nearly half of the lowercase letters that are similar in formation.
