Most of the students are participating in the lesson and are showing evidence that they are learning. One student, however, is not participating. The students are then broken up into groups and are instructed to color a picture. A short while later, it is recess time. All of the students are dismissed for recess except for the student who was not showing obvious signs of learning his colors earlier. Brad tells the student he may go to recess as soon as he can learn his colors. Before Brad could say anything else, the student correctly names all of the colors.
