It can be very stressful when you are told you will soon be given your T-TESS formal observation. To help take off some of that stress, I have come up with a ppt sample lesson that you can edit as you prepare for your own formal observation. It is a lesson you can change and adapt to your own grade level. It aims for a rating of Accomplished if not Distinguished.
I give you some pointers that have helped me obtain a higher Accomplished rating.
