You may use stickers, check marks, or whatever to mark off the box. I suggest using "o" for needs improvement and a check mark for accomplish.
Meet with the student first (after speaking with parent about the chart) and make sure they understand the skills you are looking for throughout the day.
Between you and the student figure out a reward system that the students gets excited to work for each day. For example, if you get a total of 15 checks in one day then you a tally mark on a poster. Once they get to a certain amount of tally marks then they can get a reward. Do the system for whatever works for you and the kiddo!
