You be the Proofreader

You and your friend have decided to make a fun word sheet for little children who are also learning Katakana. Your artistic friend has made the drawings for the vocabulary sheet, but did not have time to proofread it. You have a little free time, so you have volunteered to do the proofreading. Look at each of the illiustrations below and their labels. Many of the dakuten (tenten) and handakuten (maru) are missing. Make all necessary corrections by keying them into you Japanese word processor and copying and pasting the correct labels into the appropriate boxes.
