No one falls through the cracks . Language is so important for these students work with the shy students. They are more comfortable participating in a smaller group. Behavior issues are often from needs not being met. The smaller class size lets me meet those needs.
Classroom management is easier.
It's simply more peaceful. Since there are less students, we can spend more time with each parent. Less time is spent on grading, report comments, etc. There are less desks in the room and there is more space to have groups. There is less out of pocket expenses for the teacher.
