From: Rhonda GuiceSent: Friday, September 20, 2013 7:47 AMTo: Lake Cormorant HighSubject: Outside Drinks in School Teachers,No outside drinks are allowed in school. Students do not need to be eating and drinking in class. We have had two students over the past week bring alcohol into school in drink bottles so for the safety of all students no drinks need to be out during class time.Thank you for your help with this matter.RG

Hello Mrs. Chandler and Mr. Mahlmann, I enjoyed seeing you both last week. I hope your week is going great. I just wanted to give you two a heads up. Two of our school board members would like to observe CPM classrooms in the Lake Cormorant area on Monday. They will be visiting both the middle school and the high school. I would like for them to see how both of you are teaching the new curriculum. I think all of the teachers at LC do an awesome job. I just really enjoyed how you two were great at managing, circulating, and closing. I just want to give you a heads up so that you would not have a test planned. They are both very supportive of the new textbook and curriculum. Michelle and I are coming up with a schedule for Monday. I will email you and let you know when we are coming.Thanks for all you do for our students.Chereda Daugherty High School Math Specialist Desoto County Schools
