Make a picture and/or word collage of what the students believe the term "self-discipline" really means to help them express their feelings more easily than with a simple discussion. It can also help the teacher to know where to go with the lesson plan based on the students previous knowledge of the subject. Begin by writing the term "self-discipline" on the top of the blackboard, white board or even a large piece of paper or card stock. Have the children use whatever they desire to create their images; pens, pencils, crayons, markers, paint, cutouts from magazines. Complete one collage as a class or split your class into smaller groups and them discuss the various collages together.
Assign each of your kindergarten students a short list of daily or weekly tasks that must be completed in the classroom. These tasks can be as simple as keeping their coat lockers tidy, cleaning up after themselves and putting their snacks away properly. Discuss with the class how to prioritize the list and why it is important to work from the most important goal to the least. Explain how the ability to continue the pattern on a daily or weekly basis is teaching them self-discipline.
Print the word "yes" in large letters on a sheet of paper and word "no" on another sheet. Place the two sheets on opposite ends of the classroom and have the students stand in the middle of the room. Say a scenario that would require self-discipline and explain to the children that if their responses to that scenario would be yes, they can go to the yes side of the room. If it is no, they can go to the no side, and if it is somewhere in between the two, they can select the space in between that they feel is suitable. An example of a scenario would be "do you get angry when your big brother/sister makes a mean face at you?" Once the students have selected their spot on the line, discuss why they ended up where they did and how that pertains to their self-discipline.
Pass 10 pieces of paper to each student and have them draw pictures of what their dreams are. For kindergarten the dreams will likely be things such as ice cream, toys, etc. Pass around more paper and have the students roll these new sheets up into balls and then wrap their pictures around the balls. You can then assist the students in wrapping clear wrap around the balls. Using strips of paper, create stands for the balls by making a circle and stapling the ends together. Discuss with the students in which areas they will have to be self-disciplined in order to achieve their goals. For example, if it is required of them to eat all their dinner and tidy their bedrooms at home before getting dessert, this would be a form of self-discipline needed to reach the goal of ice cream.
