A problem I see within my school

Some of the major problems I see with in my school is the growth of students and no space in the classroom. When you are teaching over 30 students it can become complicated in keeping track of students who are struggling, need assistance and those that are bored. With low budgets and aids being cut from your program it is hard to meet even the students who have an IEP. How would you suggest to manage 30 mixed individuals in a 52 minute class period?
