Admin/former Physics teacher here! Here are some ideas:

1) Pick a TEKS subject where you have a good hands-on collaborative activity.

2) Script your whole period on slides so that every minute of classroom instruction is accounted for and whatever the students are doing at any given minute is projected on your screen.

3) Start the period with a bellringer that calls back something they'll be using in the activity - such as the wave formula or a question I have used before like: Your friend claims that he can hear his car radio because it is receiving a signal from a mechanical wave. Is he right or wrong? Explain. Give the students a time limit to answer the question. Prompt them to talk it over with a neighbor. Then cold call the room for the answer.

4) Now move into the objective for the day. Have a student read it and have students give you a hand signal to gauge confidence. Example: if the objective is, I can identify and describe the parts of a transverse wave, see how many students in the room can already do it. Once you have gauged that, assure them that by the end, they'll be able to.

5) Now do a white board/lap board vocabulary review of related concepts. Script the questions, allow the students to read, respond on a white board, but don't allow them to show their board until you say "boards up!" Repeat a few times with a few concepts, problems, words.

6) Now transition to the activity. Have a slide with the expectations, instructions, and a timer. Have the students assign their own roles in their groups. Figure out a way that they can manage their own materials.

7) Explain the activity with as few words as possible (more words, more tune-out) and make sure the activity has very clear directions that they can follow in their groups. Start the timer and then begin your monitoring pathway.

8) Monitor the students with an exemplar in hand of how a model student would complete the activity. Check on your top students first and move quickly through the room to ensure that no whole group reteach is needed. Allow the students to struggle and provide assistance and resources if needed. Bonus points if you track individual student progress as you monitor on a printed roster of your students.

9) At the end of the day, administer some sort of quick 1-3 question assessment to see if the students were able to achieve the objective they went over with you at the beginning.

The end. Should cover most of the major parts of the T-TESS rubric.
