  To convert an い adjective to an adverb you drop the い and add く.
  
  As in your sentence "Could you please write a little bit bigger". it attaches to the next verb 書いて, which is the connective form of "to write".

  "mou sukoshi ookiku kaite kudasai" means "Please write a little bigger." The word "ookiku" is an adverb. As you probably know, it comes from the i-adjective "ookii" meaning "big." You're not literally connecting the adjective to the verb "kaku." Instead, you are turning the adjective into an adverb to modify the verb. To change an i-adjective into an adverb, you must change the final "i" to "ku."
  
  For example, tanoshii> tanoshiku. Tsuyoi> tsuyoku. Takai> takaku. Hayai> hayaku. Yoi/ii > yoku.
  
  So, in your sentence, the adjective ookii was changed into the adverb
  ookiku modifying the verb kaku requesting how to write: in a way that is big.
  
  You can also do the same thing with na-adjectives by changing the "na" that appears before nouns into "ni."
  For example, shizuka(na)> shizuka ni. Majime(na)> majime ni. Kantan(na)> kantan ni. Benri(na)> benri ni.
  
  So used in a sentence, you could say, "Shikzua ni hanashite kudasai" (Please speak quietly).
  
  I hope that helps you.
