I hope everyone has had a good week. We have encountered many difficulties with our virtual classes. We have also had some successes. Once again, let's not get discouraged. If you are a virtual student and need face to face time, please call the office or email me and make an appointment. We are here on Fridays without traditional  students in the building and will be glad to help.  jray@tcsdms.org  or  office  233-4619.

Welcome to the new school year. This year is offering challenges that we likely have not experienced before.  This year will require patience and flexibility.  Virtual learning is something that is new to most of us and is a work in progress. We will be using google classroom. The class code for 8th science is vxo6syy to join my science class.  

If you have any concerns related to 8th science please call the office or email me.
