Not sure how things got this way...

I don't know how it happened.  After 103 teaching days, I have lost control of my students.  I am in my 14th year of teaching at an urban, culturally diverse elementary school.  One hundred percent of the students qualify for free and reduced lunch.  I taught kindergarten for 11 years, and transitional kindergarten for the last three years.  My spring break is at the end of March.  Starting Thursday, March 5, 2015 I have 17 teaching days.  My goal is to get back calm control of the classroom before going on spring break.  I will keep track of the progress I make.  Any suggestions, tips, and idea's I'd be happy to hear.  Thank you!
